haha me and my friend will def have a video camera (or at least my phone) when we test it!

thanks for the comments guys!

good news! the new boat should be much much better! plus the new boats driveshaft is 4mm thick, not 3 and the propeller is extreamly agressive and made for speed! My friend is comming over tomarrow (hopefully) to help build some more (and he has a lathe and band saw that would really help on some things. all i got in a drill)

pics so far:

That'll work much better. Looking forward to more progress!

I'm no boat expert but I think your gonna need to get that shaft much straighter or suffer from a severe vibration ?
Looks like a fun prodject, looking forward to seeing video !
Good luck Captain.

thanks! but the shaft is strait, i just had to put all kinds of spacers (aka shock pistons and 2 lst spacers lol) on it so i could mount the motor farther back, and the free spinning spacers and what's not strait.

here you go:

Nice. Get that thing to a lake so you can get a top speed!

its going to need those rear wings it has when you floor that puppy

you turned a deep single prop into a surface piercing prop!! :lol:
it like moved the water from around the prop at one stage!

that thing is gonna be farkin sick!

Yeah that seems about right... Oh, and watch out for torque-spin. :lol: We don't need any mid-pond barrel rolls.

Yes we (the viewers, not boat retrievers) do!

haha that happened today, but not becouse i hit the throttle. turns out that the boat will get up to about 15mph and start hopping on the water and it you go the least big faster than when it starts to hop, it flips :yes: anyone know of any way i could keep it from hopping and jumping on the water? but luckaly we did deal it all off with duct tape that sealed it off real well! But right now, i've got to mount the motor better to keep the motor from shifting backwards and the driveshaft from comming out :wink: so that and the fact that it hops on the water is what i need to fix, untill then, i'm only able to hit 1/4 throttle constant and bump it for a split sec up to 1/3 (and it litteraly jumps ontop of the water at that point):lol:

Maybe you can make some sort of keel.

how exactly would that work?

"anyone know of any way i could keep it from hopping and jumping on the water?"

A bigger hull.

Or less power...

Cool project... gotta respect a guy trying a 454 in a canoe!

I don't think a keel is gonna help ya Dude...

The down angle on your prop, with stock power is made to push the boat up in order to plane. With so much power you are muscling it out of the water, simple as that. You either need some kind of trims (like an airplane's elevator, but applied to water) or a variable angle outdrive.... you see why this really can't work to well. Not to shoot it down either, I think it's worthy of doing, just with a different boat.
