well, a boat that can hold 4 with a mass close to 1000 pounds, Yeah, thats allot to ask of a home made 2 hp, but what the hell, A prodject is a prodject hehehe. Figure out a portable padlewheel device and simplify the whole process hehehe. But It appears you are aware that you are building a motor that is way underpowered for the aplication its being applied too. But it will move the boat, I am getting the impresion that you are gonna run this in a Bay?. Might not be strong enough to fight current. I was thinking this was gonna be a pond lake aplication..
I am not sure of the threading for the muffler, But I am sure a simple adaption can be had, ANd it will definitly quiet your noise level allot. When do you think you might actualy have this together? It seams that most of the problems have been addressed?
