Why not use the twin carbs? They run pretty good on stock carbs.
I had it on stock carbs, but one leaked and the other had a dirty passageway somewhere and wouldn't pull fuel tru it. I ebayed them and mounted up a snowmobile carb. It works pretty good on the trailer, but for the water I have a single tillison carb that I dejetted. We'll see how that one goes.
Those who say it can't be done should stop bothering those that are doing it.
What are you using for a fuel pump?
The fuel pump is from a lawnmower/garden tractor. It's the vaccum type. 12 bucks at a lawnmower shop.

nice
Very cool build. It looks like it will be fun.
HECK OF A PROJECT!!!!...my hat is off to you...love stuff like this....obviously this is very experimental...yet, after you get some time on it...I think it would behoove you to install your rudder on the port side (or whatever direction you plan to turn) of the transom...the loads with the rudder just behind the prop will be immense and try to bend your drive at the *** end. Just my idea..but what you are doing, looks like it will be a hoot! Keep he momentium going...gg
Turnning???????????? I'll be happy just to go straight!

yeah, ya got a point there...for sure...reminds me of the Honda Trail 70 engine a buddy of mine and I tried to put in a go cart...it became too much money to finish for our shallow pockets in the 7th grade.....but boy were we dreamers...george
Well here's the good news. The experiment is in the water. Started right up and ran nice with no vibration at all. Now for the bad news,,,,,,,,,,,,I grabbed a handful of trottle and began to plane. Motor sputtered, so I idled down since I lanched it close to my house, and idled to my dock. Upon restart the starter went clunk. After checking battery connections and putting the kicker shaft back on, I realized that the motor had seized up! Back to shop. I'll pull the motor and drive and throw on an outboard I have.hydro in water 001.jpg

Well, at least with an outboard you can enjoy the boat & maybe 'back burner' the surface drive for another motor. Its a project worth persuing :I'm wondering if the demand for power over the need for motion to cool it is why it seized? By far- [real far] most boat motors are water cooled. Probably not just an availability thing but a need to overcome the always going uphill aspect of a boat & the water being almost 800x more dense than air. Wheeled vehicles have it easy compared.
