Hi guys Ok so I decided to buy a old ic cabin boat that needs quite bit of tlc but I'm not scared of a project I'm happy to get my hands dirty but I'm new to ic engines, the old owner is un aware of if the engine runs or not I haven't had it arrive yet but he's sent pictures I will upload them and show u what I'm going to be working with my plan is to strip the engine and clean it all up but as stated I'm unsure if it runs how can I check this might sound like a silly question but this is all new to me and I'm keen to learn something new I like a good challenge lol
-
:-)) By the look of it I think that motor will need a complete strip down, if you don't feel competent try Just Engines they have done motors for in the past,or could convert to electric try brushless just as fast as i.c.,happy modelling,Ray. :-)) :-))

DON'T turn it over Darren, (The engine) it probably hasn't been stored properly so the Glow fuel residue will have thickened up and the chances are, the ball bearings on the crankshaft may need replacing anyway, the piston could also be stuck in the bore. If you're going to let someone else refurb it for you, pack carefully and send it off, if you're going to DIY, immerse it for a few days in a container of Diesel (Full size) fuel.
Make sure you have the correct shape and size screwdrivers etc. before attempting to strip it down and work from the top downwards. Don't try to remove the glowplug until the head is off and give the head another soaking allowing the oil to get to both sides of the plug before trying to unscrew it, - saves a new head by stripping the threads.
Regards Ian.
Good ole Sea Scout, the area inside the engine compartment may be oil soaked.
-
Listen to Ian, he obviously wrecked a lot less engines than I have!
... I was going to say, soak the whole engine in paraffin (or the like) for a couple of days, what would you recommend Ian?
In the meantime, you can start stripping out the rest of the boat, to see 'what's what'.
Remove the engine and anything else that can be removed with a hammer!
-
I intend to do work on the engine my self well with a bit of help from my dad hopefully with u guys dads an engineer so I no he said he could clean it up with machines at work ( shan't say what company ok2 lol ) I would rather keep it as a petrol powered boat as I have my puffer and others I'm just unsure on the engine being ok
-
Tain't PETROL Darren it's Methonol based. If yer Dad's an ningineer and has the gear (Ultrasonics) to clean it with at work, it would still benefit from a few days in Diesel (Yes Martin, basically Paraffin). The fluid will help to dissolve the slime that used to be oil in the fuel that is now IN the bearings. It also acts as a penetrant for the screws.
Regards Ian.
-
Methanol based Is that what they mean when they call it nitro? Would u have a link to what fuel it would run on, boat just arrived engine feels solid so I'm thinking it's seized to be honest, dad said to ask do u no if they do spares still for this engine, engine is a os 10fsr marine gave top of it a wipe over to read it lol

Here's some more pics guys see what u think

I can't see any sort of pinion gear on the engine to drive the main gear....

Unscrew what you can and start getting it all out.
Keep it all together in a box for now.
If you start cleaning up the hull, don't use too much water, in case it starts soaking into the wood.
Use meths or turps if you have some, on old rags.
-
Hi Daren, some challenge you have there, do you have somewhere to sail an IC boat?
Len.
-
Hi I'm from swindon we have a big lake called coat water apparently we are aloud to use ic there
Martin that is what I'm concerned about there is a green cog spare not attached to anything unsure if that is the pinion but if so how the hell does it go on lol,
I love a challenge so this should be fun I can't strip anything until Monday but I need to get my puffer done before I start doing to much or my dad will throttle me as his bed room currently looks like a works yard with the amount of boats in there lol
-
Hey guys so I brought a little project a Keil kraft sea scout it came with a nitro engine which I was going to keep it nitro, But to be honest I'm going to run it electric now it's just Easyier no trouble from the genral public about the noise or smell if that makes sense.
I'm still going to clean the engine and get it running as I have been made aware that it is a rare engine well the head is and other parts are to be honest after stripping it I no I can get it running and get it looking new.
The boat itself on the other hand isn't in bad condition I have restored worse, I have removed some of the paint so far and started to take it back to bare wood finding little things like there was a random hole in the side of the hull but it's not the water pick up or exit as that was on the other side on rubbing paint back there's a brass tube but leads to nothing,
The prop shaft centre one is broke I have a brand new one so it's not to bad I may have to make a few parts out of wood but for the price I paid for the boat I'm not complaint lol.
I think I'm going to run it on brushless, I have put my puffer build on hold while I get some money up together to buy some parts and paint etc for it I hope u like the pictures I'm going to post I will try and keep regular updates :)

Here's some more
-
And more
-
Great start!
What does inside the engine cylinder look like?
-
The outlet in the side is probably for the water cooling outlet for the engine fitted before the OS and due to the age of the boat would probably have been a Diesel. The present engine may be a rarity to whoever has informed you but OS engines were the most prolific glow engines used in the UK since they were being freely imported and the water cooled head and backplate standard marine additions.
Not rare enough to keep as a pension nest egg. %)
Regards Ian.

Hi Darren
I have just enjoyed reading your threads and viewing your photos. What an interesting project this is and challenging to say the least! On a personal note I was so much hoping that you would retain the OS engine because I think that boat would be fantastic and so original sounding and looking with the IC engine brought back to life. But then I am a big fan of IC engine boats.
Just on the engine, its crankcase housing suggests to me that it contains plain bronze bearings. If so that makes the restoration of the engine so much easier with no need to have to find replacement ball races.
A fascinating project!
Craig :-))

I would say build it electric and then rebuild the engine, if anything just for the experience

But if that lovely vintage IC engine could be brought back to life.... Wouldn't it be so special to see the whole boat restored and running as it was originally? A little bit of magic in my imagination perhaps?

Reluctantly, I would have to agree with E2V, as it is your first rc boat. O0
-
The boat may be erroneously classed as "Vintage" (cos it's made out of wood in the terms of Fleebay) but a vintage OS engine??????? Not that one. It would be nice to see the boat running as originally intended but that would be either fitted with a Taycol battery sucker or an ED Bee or thereabouts.
Clean it up, fit a modern electric motor and battery system and enjoy. We''ll be onto REP Unitones and bang bang next %)
Regards Ian.

Hi again guys thank u for all your kind feed back and advice.
So dad cleaned the engine at work I shan't say what company as I don't want to drop him in it at work lol, but he's a engineer so he was like a pig in muck when I said he could do it he's told me the steps that he did he gave it a chemical dip and clean, a friend of his races ic cars and took a look he said it's quite a worn engine piston shows signs of scoring also has low compression now it's rebuilt I will try and get pictures of it when he brings it home :) it did have ball races in this engine, I believe I was told the os fp has the brass ones,
I managed to get a bit more done on the boat today before going to work this afternoon, I was advised by a friend instead of sanding the hull it should use some paint stripper on it. Never trying this before my self I thought I'd give it a go but decided I'd do it on the underneath side of the cabin roof as I thought if it all went 'Pete Tong' and it ruined the wood it would be easier to make a new lid lol :) so I done a tester and to be honest within 30 mins it had bubbled up and was blistering of I gave it a scraper over with a paint scrapper.
Then I rubbed it down gently with wire wool and some clean cold water and wiped over with a dry cloth and it was great I then just gave it a light rub with some p800 and to be honest it looks really good and so much easier than sanding it back :) . There are four little areas in corners of green which I think is some sort of resin or glue but I will work that later I decided I was going to do one part of the hull with stripper to see how well it took on all the layers of paint, to be honest I new it wasn't going to be easy as there's so many. I left I soaking in for 2 hours just so I knew myself it was probably done enough I followed same method as before scrapped, wire wooled, dried rubbed with p800 and I have to admit it is such a beautiful little hull under all that paint the wood is lovely and it's been built pretty well considering the age of the boat. You'd think the wood would be bad but I no some more recent model boats wood ones in worse condition I'm not saying it's perfect there's still areas that need work but it's brilliant very happy I paid £30 for this boat and £20 delivery not a lot really :)
Hope u guys enjoy sorry if I chat on a bit lol :) here's some pics of today's work ....
-
Paint's done it job then, preserving the wood.
Not as I always think, make it look pretty!
-
Again, chances are when originally built, it was painted with "Valspar" or "Dulux". O0 :-))
You may need to use a surface preparation that sucks the oil out of the wood in the engine compartment Darren, IC engines are/were sloppy little b*****s despite exhaust fittings.
Regards Ian.
-
My hats what paint I was assuming it was as it's on there very thick,
Yeah me and dad were only on about that last night :) I always thought that too Martin
-
Hi guys
More work done stripping paint of of with the paint stripper on the hull there's still some paint to remove round the bow and keel but I will remove this by sanding it down overall the hull is pretty good under paint it will need some work done in places,
Ul see I removed the prop shaft I noticed it to begin with that it had been fitted squint but thought it would be ok but decided to remove it and fit a new on correctly :)
I have now removed all paint of the lid and resin :)
-
Hi Darren
I must say I think you are doing a splendid job here. Thank you for uploading further photos as it shows the developments in a very interesting manner.
Keep up the excellent work!
Craig :-))
-
Thank u Craig I'm back round at my fathers tomorrow so I'm planing on having all paint removed from lower of the hull so then I can turn my attention to cabin and cleaning the inside
-
Hi guys more work done today with help of my apprentice lol ( my nans dog jack )
All paint is now removed from the hull accept a little bit around where the rudder is and round the shaft supports that have now been removed the hull is overall in good condition and I'm quite happy there will be a few areas that will need attention with filler but it's looking good had a little bit of a play sanding the top deck just to see how well the varnish would come off and removed bit on cabin as well overall it's going well :)
Dad also brought the engine back from work I have tracked down a new piston for it from my local hobby store as he has spares from years ago and because the piston that's in mine is worn I'm not going to use the engine but I'd rather keep it and no it will run fine if I decide to use it in something else
-
And some more

As much as I am enjoying seeing the restoration of the boat, I have to say that the photos of your OS engine depict a remarkable transformation from what it looked like originally! I do hope that some day you have that engine back in use. Exciting stuff indeed!
Craig :-))
-
Hi Craig sorry haven't replied been busy with work and when it's not work it's the wife, I can never win lol, the engine will be used we are always looking in to it for out next project :)
Any way I got a bit more work done today basically I decided where I ripped the bars out the roof to fill these I'm thinking of going for a Italian cabin cruiser style unsure yet, as I said I filled the holes and rubbed back gently then went over with some p800 just to smooth it off, there are quite a few imperfections that need to be worked I'm going to spray a coat of primmer on at some point so I can see more where they are my father says it's fine and it's wood ul never work perfect and paint will hide a lot but personally I'd rather it was spot on.
I filled the hole where the exhaust come out with some old scrap wood I had must admit done it poorly but where it was going to be covered with a few thin skims of filler which I done as u will see in pictures I also started work on a new bulkhead part where the servo gets hidden due to orignal one brakin of decided to have the part where the servo sat in I also had my nans little helper again jack the dog lol I hope u enjoy the pictures I'm going to hopefully be going to dad 2mora so I will try up load more pic

Hi guys not much more done on the boat to be honest as I'm tired due to work, joys of working for a big named supermarket supposed to finish at a certain time and u end up having to stay on just put in a 68 hour week tired is not the word lol, but I been bidding on a brand new water cooling brushless motor 2075 kv motor that I will run on lipos bit of a bargain to be honest as it's brand new :)
-
Hi Darren,
I would stay away from the amphungry FSD motors if I were you.
It's a two pole motor with a poor low end response, meaning you can't run it dead slow, as it 'll burst into life at one third throttle.
Also, 2075KV will give you 15000 rpm on 2S Lipo's, which is rather a lot on a subsurface prop, rule of thumb is not to exceed 10.000 rpm, to avoid having a blender under the hull (and little forward motion).
Not knowing the size and weight of your boat I can't make a suggestion which motor to get, but a four pole inrunner, or, even better, a multi pole outrunner will work nicely.
Check out the video of my 110 cm MAS hull, powered by an 800KV outrunner on 4S, turning a 60 mm two blade prop:

(Turn up the volume really high to hear the running noise.)

...joys of working for a big named supermarket supposed to finish at a certain time and u end up having to stay on just put in a 68 hour week
Story of my life. I work in the petrol station and as an online delivery driver for The Supermarket With Orange Bags, and I've just done 55 hours over the 156 I'm contracted to do per four-weeks. Christmas saw me do a seventeen-and-a-quarter hour shift: a personal record. Fifteen-hour shifts are not uncommon. As I'm in training to be a Team Leader, my half-hour breaks tend to be five minutes. This week I'm on holiday - and have four days at work. %% The week after? Seven days at work.
It's insane.

Hi guys and sorry I didn't reply been a night mare at the moment with work :-/
I did manage to get a little bit today and yesterday but I have ended up picking up more projects lol ( just brought a brand new billings slo mo shun and a second hand pilot boat lol), I decided after thinking and reading pompebled stated about the motor to go for a different one either way it will be water cooled :)
So on with what I have managed to get done well I rubbed all the lid back and used some p1200 just to prep it for primer I then used some primer and as expected it showed the areas which need work which isn't a problem I expected the boat to need work, as we had a lovely day of weather yesterday I managed to get out in the garden and do some more sanding most of the boat is sanded now I just have to do a little bit more to the deck and then the inside :) I removed the rear bulk head I fitted I'm going to a different way with it I think :)
I was having a look at the hole on the side where there was a bit of brass I pushed it gently and it came straight out so I used a circle bit of wood to fill it, it just needs a bit of filler to finish it of but she's getting there, my rudder arrived for her I ordered slightly to big rudder but my way off thinking with this is if I order bigger it can always be grinded back to a smaller size :)
Fitted the inlet and out let for the water cooling as well just waiting for the prop shaft to arrive, hope u like the pictures and again I'm sorry for the delay of updates
-
Ok guys just a little update I haven't really done a lot to the cabin cruiser as I got side tracked with my new project lol
It's a hovercraft, I have been signed off work for a week but after being back to docs today been signed off for a further two weeks so I'm planning on getting the cabin cruiser progressed more here's some pictures of the hover craft any way colours are a bit funky and bright didn't quite no how bright they were going to be until they were on lol ( only the cabin has been started on the hover craft )
-
Started doing some more on the boat this week boat is now under coated in one coat of grey just so I can see where I need to fill and then I will spray her with white undercoat, I brought a new prop shaft for her as the other one that was in it when I brought the boat was fitted badly but it's actualy the keel that's out on the boat so I done the best I can with fitting it it should be ok I no it looks a little rough at the moment but I will sort it all out, rudder needs trimming down and I have fitted the new motor to its plate it should be a good little boat when it's done :)
-
Hi Darren,
The hull starts to look the part.
Which motor did you select?
Keep in mind, 10.000 rpm under load will be already very fast...
Regards, Jan.
-
Hi I brought two of these motors one is a 3600kv motor and the other is a 1500kv I decided to go for the 1500kv with a 7.4 two cell lipo
-
Nice, that would put you right in the sweet spot (10.000 rpm).
Assuming it's a Ø28 mm motor, you should have room under the hull for a sufficient large prop to make her fly (depending on the pitch).
Regards, Jan.
-
Hi yeah I have an older prop my father has gave me I was going to try to begin with it's a 35mm 2 blade x prop :) still have a lot to do on her and my other boats at the moment seem to be running out of time tho lol
