Yea i did think of trying the boat as is but she is a bit heavy at the back so im a little scared to be honest,im sure the speed will be a lot better but i think she will be to flighty.Wont get her out befor exmas so i thought why not just move it now ready for the new year.I might hold off doing it just yet and see if i get a chance to run it and see what happens .Glad to hear your Panther is close to your magic number thats good ,look forward to the video mate.A local fella just contacted me hes bought Daves mercury cat with a zen 7 that thing should motor so were gonna hook up sometime.This is his first boat ,hopefully it wont scare him too much lol  :o.

Go for it, the throttle goes both ways, you can always back it off if it gets out of shape too much....

Hi guys,

I have not got any of the farst craft you chaps run but I have been reading this thread with interest. restricting the water flow on your engines is a very easy and adjustible item.  pop down to your local aquatic supply shop and get some air pump valves. these are adjusted by screwing down or up a tapered threaded valve. I think it would give you the adjustment you are after depending on weather conditions.

Now to throw some ideas to increase power which I dont know if it would work on model size engines but yes you need the cyl temp to be hot enough but then colder intake air gives out better performance (intercoolers)
could you have the first influx of your cooling water run around your intake filter then to the exhaust then to the jacket then out or am I getting this ALL wrong.
Forgive me for my ignorance of your type of craft I'll keep quiet if you think I should :-\

Not at all Catengineman. You are correct in your statement, when the air is cold and damp is when the best power is made, most of the motors we use are unfiltered on the air inlet, the carb is open into the hull.

Not sure charge cooling would be beneficial, unless, of course, forced induction were being used.

Speaking for myself, all ideas are welcomed.

Thanks for that however this is a discussion forum, if someone believes a certain piece of information is unsafe then they should post in the thread, that way it reaches all that read the thread. Generalisations such as this do not promote discussion and do not highlight the allegedly suspect/unsafe items.

Other than that, good reminder however I believe that the gist of what you are saying is understood by forum members the world over.
