[Tomzeren]

Hello Again...

I am posting a picture of my hull if anyone are interested in my project. The hull looks kind of bad now but I will fix it ..I thought that it also might would help you guys to specify an engine-size for me ???If you have advices or questions to me, add a reply and I will answer as fast as I can.. ;D

Here are the dimensions of my hull again:

Lenght: 74 cm

Lenght in water: 67 cm

width: 25-26 cm

Weight: 2,5 - 3 kg

Thanks,

Tomzeren! ;D

I'm no expert but I would say with a 30" boat you wouldn't want to use any more than a .21 (3.5cc) engine.

A .21-.35 would be plenty to push this hull along nicely...but ultimately...the sky is the limit. I personally am a big fan of overpowering. (Sometimes maybe..I get carried away ..I'm told)

You could easily fit a .40 or maybe a .60/.65.

It would launch out of the water and get up on step instantly.

You wouldn't necessarily get to use WOT in anything other than quick 'shots', (and a shot at the wrong time hitting rough water will easily=airborn/upside down)..but it's a ton of fun...and makes for great conversation. You would also probably need trimtabs to maintain reasonable control over 35mph...or every time you hit a wave and the nose comes up..the prop will try and pass it underneath. :'(

Good luck...let us know what you decide.

Thank you for your advice...

It helps me a lot! ;D

I cant afford to much right now so i have to find an engine that doesn't cost to much, and thats why i am thinking about hammerheads offer..I dont have that very much experience with steering model-boats yet so i think i will start with something that stays in the water and maybe later i will put a more powerful engine in it...I'll let you know what i decide to buy...

Thanks,

You can use aircraft rc engines if you need to keep the cost down. It is extremely easy to convert them to marine use...and they are often a 1/3 the cost or less on e-bay.

Engines with a completely round upper cylinder/head work best.

Use small steel brake line, and wrap it around the engine head. (3x is plenty) Use a long piece, start in the middle, and cut when done. Once cut, you will be able to tighten a little more like a spring. Use a large hose clamp around it (Rad hose clamp)

You can cool the crankcase by making a cover for the existing one (square tin or copper) with in/out water tubes on it. Drill holes and use the existing crankcover bolts to hold it on.

This works A1! and makes things alot more affordable.

Hope it helps..
