Title: Linda Carol Moran build
Post by: CaptTex on July 11, 2015, 01:34:50 AM
Welp she came in! So far last night I got the hull and stand completed, a slow start but I'm gettin there! She will follow the original Moran color scheme (fingers crossed I get it right) and have LED lights for the mast, nav and deck lights supplied by Umi, they are of great quality and I highly recommend! I used Testors plastic model glue for the initial hull seam and with the fiberglass tape down the center, was this proper? Does anyone have any ideas on how to get a metal gear off a motor? I've thought of a couple ways but I'm scared too much violence will damage the motor. I welcome all questions and critiques, hope you enjoy my build!

Hi CaptTex
First make sure it is not part of the shaft ,you do not say what size it is, if there is room wrap a wet rag round the shaft between the gear and the motor do not let any moisture in to the motor and then warm the gear with a gas torch DO NOT GET RED HOT , then try and tap of the gear , or pull of with grips , it's hard to try and give you some pointers when we ca not see the set up ,this is my opinion others will have different ideas .

Do you need the gear ? If not use a hack saw and cut carefully in to it. go down till you touch the shaft . a diagonal cut is best front to rear. With the gear weakened it will come off .

No I do not need it, the only reason its on there is because i salvaged the motor from another RC. Thanks for the advice! I'll give both a go!

Ok well hit a little bit of a snag tonight, finished the hull and put in the stuffing box with support and sanded down the hull ready for the keel strip (no leaks thank god!) However I've hit a little problem, the circuit board pictured is the "brain" of the whole operation, however it occured to me on the helicopter it came off of, the throttle is 0-100 in one direction not 0-100 in both forward and reverse which is what I need! Any pointers? Until I get the electronics figured out and put in I can't move forward! For reference the equipment came off of a MJX FX 45 helo.

Post by: CaptTex on July 13, 2015, 04:56:24 AM
I was looking over the hull just a few minutes ago, and notices some deforming down the keel and also where i put the stuffing box support, I'm thinking its the glue?






Tex
Title: Re: Linda Carol Moran build
Post by: CaptTex on July 15, 2015, 03:15:01 PM
The keel strip has been fitted, the cabin is constructed and bondo has been applied to even out the seems. Along the keel strip I have also applied bondo, which will be sanded down and to correct form to hide the damage the glue did. Holes for the lights have been cut out, and I'll begin soldering electric parts soon. Electronics will go into place once I get the new reciever/transmitter/esc/battery, so for now I'm making her aesthetically pleasing!

Good Start.  :-))

Yes, too much glue can be a hazard.
But it sounds like you have manged to find a suitable filler.


Pick up a an Mtronik ESC from Harbor Models over in California.
That should work well for you. You can plug it directly into your reciever, and the BEC
will eliminate the need for the small reciever battery.

Post by: Brian60 on July 15, 2015, 08:13:59 PM
A diamond cutting disk (cheap as chips on ebay) for a rotary tool like a dremel is the best for getting the gear off the motor shaft. Carefully cut between the teeth almost but not quite down to the shaft. This will relieve the pressure and it should pull away with a pair of grips.
Title: Re: Linda Carol Moran build
Post by: CaptTex on July 15, 2015, 08:25:50 PM
Thanks you guys! On tap for tonight is most likely fittings for the flood lights and starting the wiring so I can prepare it to be connected to a switch and ultimately to the battery. Might give the motor thing a go, we'll see how brave I feel  :-) , also sanding and completing the cabin, maybe even the rub rails on the hull! It seems however that I'm missing the rudder tube, gonna have to fabricate my own i suppose!

Welp finished the deck lights, sanded the cabin and did some more work on the hull. The deck lights took forever, but turned out rather nice under a magnifying glass and filler! Attached a resistor and ran a test the lights will give her a good glow! On tap for tommorow finish the wiring and install the lights, put on the rub rails and hopefully the cabin roof and prime it!

Got the lights installed and almost finished the wiring, since this one piece of the ship is taking so much time I've decided to concentrate my efforts on her. After the wiring is installed I'll cut port holes and place clear plastic bh ind them so there is "glass" and the light behind the LEDs will shine through! Then the stairs, roof and doors/hand rails then I'll move on. My inexperience is clear in these pictures!

Alright folks, made a good amount of progress! Continued cleaning up the hull and installed the rudder tube and assembled/primed the rudder. Continued work in the cabin and cleaned it up, as well as fitting the servo. Next up is wiring the lights and beginning work on the wheel house and other details.

Title: Re: Linda Carol Moran build
Post by: escipion on July 23, 2015, 09:38:13 PM
Hello Tex!!!!
When she made her first sail, I had to add weight mostly in the stern.
In my Carol the water only covers the waterline. Although she is small, she have no problems even when there are bigger boats sailing. I believe that, as the real tugs, sitting lower will depends where she will be sailing.

Best regards

Post by: CaptTex on July 24, 2015, 08:53:42 PM
Well mostly protected ponds and estuaries, no heavy waves or anything of the sort so no reason to have her sitting high in the water, but when I see videos of tugs like her in real life they sit relatively low. I have a friend that has a 12 ft kayak hes gonna let me push around  %% , hoping she looks good under way and in pictures! I also bought a turnigy reciever switch so i can control my lights on my transmitter, but im wondering how do I assign that function to one of the switches (its a fly sky 6 channel).




Tex
Title: Re: Linda Carol Moran build
Post by: escipion on July 24, 2015, 09:37:13 PM
I believe that if you feel uncomfortable, maybe sitting her 5mm more will be ok. You can add her a small vinyl line above the waterline to sign the level.
Title: Re: Linda Carol Moran build
Post by: CaptTex on July 24, 2015, 09:39:01 PM
Ill go home and water test her tonight and see where I want her at, I'm not sure why but a low sitting tug boat has always looked good to me! Thank you sir.

Ok I've hit a snag, was making major steam on the wiring and went to test once I was finished.....only one worked. So took it all out and just soldered resistors on the LEDS and only one still works.....are the rest blown? Or is it possible the prongs are dirty or maybe the resistor is backwards? They all had resistors when I tested the finished wiring so I don't think they're blown.








Tex
Title: Re: Linda Carol Moran build
Post by: Umi_Ryuzuki on July 26, 2015, 07:39:37 AM
It shouldn't matter that which way the resistor is wired in.
There is a positive and negative lead to the LED.

The long lead is Positive, you didn't accidently hook them up backwards did you?

Tex
Title: Re: Linda Carol Moran build
Post by: Umi_Ryuzuki on July 26, 2015, 07:20:26 PM
Could be a bad LED, is it a different color, or just dim?


 {:-{
Title: Re: Linda Carol Moran build
Post by: CaptTex on July 26, 2015, 07:41:19 PM
Just dim, not a different color though! I'm hoping maybe my soldering job is just poor cause if its bad that is a lot of cutting and refitting....

Tex
Title: Re: Linda Carol Moran build
Post by: Tug-Kenny on July 26, 2015, 08:58:53 PM

Once they go dim from excess voltage  (but not enough to blow them) they stay dim and cannot recover.

Ok folks pictures will come tonight, the hull was primed painted and got the towing bits and side mooring bits in place. the pilot house is under construction and wiring is coming along nicely! I have a 3000 mah NIMH battery its got roughly a 540 motor I think? What kind of run time am I looking at bout an hour in my mind?




Tex
Title: Re: Linda Carol Moran build
Post by: escipion on August 04, 2015, 11:51:54 PM
Hi Tex!!!!
One observation, a 540 motor isn't too big for that boat??? the instructions said that a servo could do the job, but I felt that's not enough so I use a Dumas 4.8V motor and works really fine

http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXE550&P=7

Maybe a 300 is ok.

Well. that's my opinion

Best regards
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 05, 2015, 12:07:45 AM
This is the motor, maybe it's smaller than I think! A lot of progress has been made, mainly just tidying up and finishing wiring now. My main problem is fitting "glass to the windows of the pilot house and cabin, ideas? I also have two 7.4v 2s lipo ps is im going to put together to provide power for the lights since I don't think 1 3000 mah 7.4v NIMH will do it all by itself. I'm really focusing on making her presentable, like it looks like I've put the time and effort into her! Still to come is the brass mast, that's a surprise for yall  :}




Tex
Title: Re: Linda Carol Moran build
Post by: escipion on August 05, 2015, 06:06:07 PM
Hi Tex!!!
Nice work  :-))

For the windows there is a glue called "Formula 560" from ZAP products, it's designed to glue canopies to the RC airplanes, is very strong and do not generate fumes as the CA, when it dries it is almost transparent, I used it in some of my boats and gave me good results

Best regards
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 05, 2015, 06:55:14 PM
How do you set the glue up in the windows? Thanks I'm really proud of it so far!




Tex
Title: Re: Linda Carol Moran build
Post by: escipion on August 05, 2015, 07:13:13 PM
Hi Tex!!!
The glue looks like the common white glue, so I made the window a little larger than the frame, put the glue in the interior of the cabin where the window should rest and keep it clamped for at least a couple of hours

Best regards
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 05, 2015, 07:15:21 PM

Tex
Title: Re: Linda Carol Moran build
Post by: Umi_Ryuzuki on August 07, 2015, 05:55:31 AM
Use a good "flux".
KESTER makes a nice  "self cleaning solder paste".
Place a dab on the two pieces to be soldered, heat your
soldering iron, clean up the tip, then melt a bit of solder onto the  tip of the iron.
Touch the melted solder to the joint, and it should "wick" into the joint almost immediately.
Note: solder flows toward the heat. So if the solder is stuck to one side of a joint,
apply the heat to the opposite side to melt the solder and get it to flow across.

Post by: CaptTex on August 07, 2015, 04:00:47 PM
Gotcha! definitely useful info Umi thank you, and my lights came in look great as always!  :-))  I'm actually thinking about "cheating" and using this awesome adhesive my local hobby store sells, holds everything stupidly strong! This weekend will be a worl wind of activity in the ship yard!




Tex
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 08, 2015, 03:27:52 PM
The soldering took a little longer than I thought, the actual soldering didnt take long once I got flux (dumb me) it was the set up with risers and taping pieces in place that took a while. I started on the mast last night but the I can't get the resistor/wire/lead of the LED down the mast so I can solder it up, does anyone have any tips? It seems that the electrical tape is not helping, but I have to insulate it otherwise it'll arch with the mast which is doubling as the negative return.

You can shorten up the resistor leads, just be careful not to
over heat and burnout the resistor when soldering.
A little bit of rubberized paint, like tool dip, or liquid electrical tape should
then be enough to insulate the remaining wire.

What size is the mast , I have the wires down the inside of the mast for all the lights on Fairmount Alpine. I used the wire from the coils off the hard drive from a old computer ,the enamel  on the wire is the insulation I then bought some insulation varnish from RS Componants , just run the + down the inside and solder the -to the brass near the light ,the resistor were put on a piece of variboard ,and the- tagged on to the bottom of the mast . My mast is 2mm OD ,took me about a month off and on to build and wire up . If you try this don't rush and feed the wire in easy as not to scrape off the varnish ,I just revernished the wire when it happened to me and started again , and keep testing as you go . I only had one fail and that was the anchor light and because the wire is so thin I used CA glue and then painted the mast it now looks like a cable duct running up the mast .As you will know the resistors need not be close to the lights just in the circuit .
Good luck

Post by: CaptTex on August 10, 2015, 12:24:37 PM
I got the lights insulated up and installed into the mast, soldered and now im waiting on the putty to dry so I can shape the "pedestals for the lights on the mast! Last night before bed I finished the glass work on the pilot house, and now that will allow me to put the finishing touches on it and touch up any paint! Thanks for the info guys really appreciate it! Work continues in the shipyard tonight :)

Post by: CaptTex on August 11, 2015, 04:53:28 PM
Howdy folks, so quiet a bit for yall to mull over! Ive almost completed the pilot house finished the railing and prefitted it on the cabin which is almost complete but needs a couple more details. I started work on the funnel, and had a thought since she was a diesel tug maybe had aux engines so added my own touch to her. Fitted the glass to the pilot house and painted the moulding around it, a couple of touch ups and adding the stairs and railing to the pilot house she'll be ready to roll! For the mast, I did small brass tubing and cut holes in the mast, installed and soldered the wiring then proceeded to use squadron green putty to mold pedestals for the lights, once dry I sanded and shaped until I was happy then it was off to paint! Wiring will continue tonight, My charger should arrive so I might have a couple of pictures from the hull making a shakedown cruise  :-))  Hope you are all enjoying what is quickly becoming a kit bash!




Tex
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 12, 2015, 04:31:34 PM
And more progress! %%  The cabin was given a final sanding, the holes for the railing fitted and the funnel support plate and hole for the life boat arm was drilled and sanded, lights have been taped off and she is ready for paint  :-))  Whilst in a fit of sheer brilliance, I forgot to fit the flag arm (correct me if I'm wrong) to the mast. So I sanded down the mast then soldered the arm and re-primed the mast, good to go now! The funnel was primed and drying, but I had an extra light from Umi, what shall I do with it? I'm gonna make an extra work light, You can see it drying in the background of the funnel picture! I wasnt happy with the life boat arm, so I cut two pieces of brass tube and soldered them together, it is also primed and ready to go. The lifeboat is pretty boring, standard out of the kit but looks nice primed up. The stairs were a trick, only 2 sets of them were supplied so you had to make the other two, and the instructions werent clear so I may have free based just a little! And just to top it all off, a couple more views of the pilot house and one more of the mast! Hope you Enjoy the pics!

Tonight before I put on the paint, I was wanting to put in some ventilators. And as the kit supplied one does not provide any actual airflow, I want to make my own. Something modern like a square vent, but I can't find a suitable picture. Can anyone help out with this?

TugMad, I admire the Big Carol Moran pushing the little one on a stiff towline.


And BigTex I would think your Little Carol would do well handling a good size, heavy barge, given she seems to have a barn door for a rudder.

Post by: CaptTex on August 12, 2015, 10:01:52 PM
Hopefully so! Next pay check will be materials for a barge! I think she is slightly over powered, but can be kept at scale speed at the helm  ok2 . Probably the only progress tonight will be ventilators and priming, since I have to wait for that to dry completely it kinda limits me. However my charger finally arrived today so might get a run with just the hull tonight, after it cools down. Dave I'm seeing 106 here in College Station.

Yeah, same here.  Too damn hot.  I wonder if our plastic hulls will survive the heated air and hot water.  My only other model boat experience was up in Washington and British Columbia where the air and water seldom exceed 70 and 50F.


I do remember my earlier days of shrimping on Galveston Bay.  On days like this you pulled in your net and the shrimp were already boiled. O0

Hahaha there ya go! All we need is some sauce! Honestly I think we might need to coat them in lead? maybe iron? Best way to protect em! Just plugged up my battery and im already getting ansy....Do you think modern ventilators on the carol moran would look out of place, I feel like she is one of those boats who was in between new and old design?




Tex
Title: Re: Linda Carol Moran build
Post by: CGAux26 on August 12, 2015, 10:41:12 PM
Ventilators:  As modelers always say to each other, do what you want, it's your boat.  But my 2 bits is that square ventilators may look out of place on the Carol Moran. 


My friend Joe up in BC made several vents for me from ⅜" plastic pipe els for my barge.  I hunted all over and can't find the pictures.  But they would be too big for your Carol.  Still, the traditional round goose neck vents are good.  They can be made open at both ends to allow air to circulate in the hull.
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 12, 2015, 10:44:24 PM
But the piece I have is solid metal, and in such a way hollowing it out would be a nightmare! Maybe Ill just stick with this one, but I figured airflow would be a good thing, though I dont know her operating temp under heavy load or just cruising yet.

Title: Re: Linda Carol Moran build
Post by: CGAux26 on August 13, 2015, 12:23:12 AM
My Springer tug, about the same size as your Carol, has no ventilation into the hull.  It runs on a Speed 600 motor, direct drive, on two 6 volt SLA batteries in parallel.  It turns a 40 mm 3 blade prop.  The motor and the ESC get just barely warm to the touch after 1.5 hours' running time, at various speeds.


My Jim Wilder tug has a slightly larger diameter motor of unknown pedigree, which turns a bit slower in direct drive, but on a 12 VDC SLA battery.  The prop is about 2", with 3 blades.  The cabin has 2 small portholes on each side, with no "glass" in them, so there is some air circulation.  The vent arrangement on top of the cabin is arranged to mainly feed air to the smoke generator.  Again, no  noticeable heating of the motor, ESC or battery.

Post by: CaptTex on August 13, 2015, 04:25:28 PM
So alot of stuff went into paint yesterday, finished the pilot house, finished the mast, the funnel received a second coat last night so its still drying. The lifeboat will be painted in the same scheme as the tug, so that will take a bit! Now on the the "fun" stuff....took her out to the pond yesterday with a full load of ballast and a full battery...kinda sat a little weird in the water so I adjusted and when I was happy pushed her away and gave it some throttle. Responded nicely for about 10 seconds then a high pitched whine, and no response from the prop....great I spun on the propeller...nope thank goodness the coupling just gave way! So I've been informed about a dog bone coupler and will be looking into that soon! Enclosed is a pic of her sitting dead in the water, it's a shame the break down occured we had a 16ft kayak we wanted to push around! Hope you enjoy the pics all questions are welcome!

Got the pilot house, cabin, stack and mast assembled last night as well as the lifeboat support arm. Paint is drying at the moment but forgot to snap a pic for yall today. Until then here is another teaser of the lights, I ordered the coupling and a new brass prop today so Hopefully she will be good to go soon! Until then I've hit another road block, installed the turnigy receiver switch last night into a lipo 2s pack and then plugged it into the receiver and no good....I looked at the instructions and apparently you have to cross the negatives if you are running a 2 battery system, 1 for the lights and 1 for the receiver. The only problem is one is a Lipo and the other is a NIMH battery, I'm assuming you cant cross these? Any help would be appreciated, and as always all questions are welcome hope yall are enjoying it!

Sorry guys, im a terrible progress recorder. But she is complete, a few paint details and repainting the water line.....she was sitting too low. My dog bone and 30mm brass prop come in Tuesday, the engine actually keeps loosening in the fuel tubing when put under heavy load! I'll post pics of the wiring and explain thrthe turnigy switch if anyone would like me too! Dave she's ready to go!

Nice work Tex  :-)) congratulations

I recommend you to paint, or put, the small white line around the hull , really makes her look different

Thank you sir! Yeah I might have to do that! I'm working on towing gear and bumpers right now, I've been looking at other kits and they are so expensive! I'm wanting to do a tractor tug but i don't know if a hull and scratch build is the way to go, I did enjoy making custom parts for the Carol.

Not a lot of real tugs have waterline stripes.  You might want to check what the original boat had before deciding.  Plus adding a waterline now means taking everything out of the boat so you can turn it over and mark the waterline.

Post by: CaptTex on August 17, 2015, 10:33:35 PM
That would be a pain! Considering two batteries, engine, esc, servo and switches......she is stuffed with equipment not to mention ballast. I'm actually going to swap two of her 8 oz weights for 4 oz replacements. I do like the line though, makes her stand out.

Hello!!!
Don't know if you are talking about the line I recommended, It's not the waterline, it's the white one that goes around the hull at the deck elevation, the original Moran's tugs have it

So the shaft side of the dog bone is still slipping from the set screws grip, I'm at a loss guys any ideas?

Use a metal file to cut a flat spot on the propeller and motor shafts.

Set the coupling where you want it ,take out the grub screw and mark the shaft , remove coupling and the drill a dimple into the shaft , just the depth of the drill angle so when you build it al back up the grub screw will go into the depression , when it's home put another grub screw on top so that it locks it in.

It's one problem after another....fixed the coupling and tub tested her, outstanding amount of thrust with the new 3 blade 30mm brass prop! Threw water everywhere, she could handle full astern on the transmitter, but all ahead had to be moderated to maybe 1/4 on the tx. Then......smoke! Shut everything down and checked everything, the motor literally burned me when I touched it......the motor came off a heli and I don't think it's brushless because it only has two leads, it was powered by a 7.4v 2s lipo, ideas? I didn't think the power source mattered, could be wrong she currently has a 3000 mah 7.2v NIMH as the main power supply.

 It has nothing to do with the battery, or other equipment.
I would say too many RPM trying to turn a large propeller.
Just too large a load for that motor.  {:-{

Title: Re: Linda Carol Moran build
Post by: CGAux26 on August 19, 2015, 02:01:07 PM
Are your batteries wired in series, giving 14.4 volts?  For what voltage is the motor rated?  That would account for the very high RPM and extra load on the motor.  Wiring them in parallel might be the solution.
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 19, 2015, 03:58:15 PM
Only one battery is powering the motor, the motor is actually bigger than the propeller though thats what surprises me! The motor originally was powered by the 7.4v lipo battery that came  with it from the factory so I would assume its rated for 7.4v and I think its even stamped on it, I know it sounds crazy but i read on here somewhere the motor and the propeller diameter must be the same if not the propeller smaller.

Hi Tex!!!
That happens when the motor have to work with too much load, not necessarily the propeller load, could be that something else, like a bad alignment of the motor, but you solved it with the dog bone, another thing could be the shaft or the tube that contains the shaft is not straight.

My advise, remove the coupling system and turn the propeller with your fingers, if it moves easily, then install the coupling sockets and check that they are not grazing against anything, then install the hole coupling system ant turn again the propeller with your fingers to notice if there is not too much difference in load with the hole system assembled compared with only the shaft and the propeller

Best regards
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 19, 2015, 04:54:05 PM
The shaft is greased fully and turns easy, believe it or not that was the first thing I checked. Am I correct on the two leads indicating a brushed motor? I'll double check when I get home, what did you power your carol with?

Title: Re: Linda Carol Moran build
Post by: escipion on August 19, 2015, 05:05:13 PM
Hi Tex!!!
I powered my carol  with a 4.8V Dumas motor, a silicone fuel tube as a couple, and two 4.8 batteries, one for the motor and the other for the receiver, didn't change the propeller, installed the plastic one who came with the kit

Sorry, don't have photos of the propellers site alone

Hope you fix the problem


Title: Re: Linda Carol Moran build
Post by: escipion on August 19, 2015, 05:09:30 PM
I'm not an expert as other guys in the forum, but as I see, yes, your motor is brushed
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 19, 2015, 05:46:03 PM
Beautiful boat escipion, I'm not sure what the problem could be then! Maybe it just runs hot naturally, as stupid as that sounds but I am not willing to risk burning her down or causing toxic materials to be in a pond if she burns, the quest for answers continues!




Tex
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 19, 2015, 05:50:11 PM
By the way I'm not sure if this is helpful or not, but the receiver controlled switch is of course naturally hooked up with neg and pos to the lights but in order for the switch to work you have to have a common ground and run a secondary neg wire to any neg leg on the receiver, I'm positive this isnt over charging anything because there isnt another pos going to the main propulsion circuit.


Tex
Title: Re: Linda Carol Moran build
Post by: CGAux26 on August 19, 2015, 06:25:55 PM
I think you may have your switch wired wrong.  A switch goes in the positive wire, and is there to interrupt or allow the flow of positive electricity.  The Turnigy switch has 2 red wires on one end, that connect between the positive feed from the battery to the plus side of the lights (or in my boat to the smoke generator.  The wires on the other end of the switch go to the receiver, so the TX can control the switch. 


The switch is at left in the picture.
Title: Re: Linda Carol Moran build
Post by: CaptTex on August 19, 2015, 06:29:57 PM
I tried just wiring in neg and positive on the switch Dave, but no luck it wouldn't power up....so I found a instructional video that said add the ground to the neg pole on the receiver. The extra neg or "ground" as the instructional video showed, comes off the negative of the battery, this is set up this way because I'm using 2 batteries, unless im doing this wrong. the video is on Youtube, if you wanna take a look Dave.

Took a few pics for you fine folks, managed to keep her cool long enough to snap a few! Enjoy  :}  Dave I'll be calling you tommorow to chat about the issue, I've been spending time with the ol ball and chain today which is why I've been away from my email! I actually saw that model but I'll be buying their discounted shelley foss and turning it into a free lance tractor tug, probably for Moran Towing  %)

What was the cause of your motor overheating?  Did anything else overheat, too (wires, ESC, etc.)?

No that's the odd thing, no heat anywhere else just the engine. Still no idea Dave, thank you escipion! Maybe it just wasn't meant for marine use, but I don't know why it would matter?
