OK, lets see what I have learnt. I am ordering Canadian airboats plans for a welded aluminum 8' by probably build it 17'. Some of the design isn't as nice as Farons boats, (I still like that green one in your brochure). Chev 454 mounted down low with a long belt driving a three blade master Blaster would be optimum. I guess price of the prop is my biggest concern, it's more money than i'm going to spend on the engine! Polymer on bottom and lower sides mounted with large head aluminum rivets. Operator at back, a little more over the engine than the green boat, side by side buckets with stick in middle? Quad bucket up front. I dont know if I can talk my buddy into building the reverse rotator unit, he was concerned about size of market for amount of R&D. He builds oil field stuff and except for some of his products that are already in production, most work comes on a CD or he writes code from specs and blueprints. I agree, one boat doesn't do it all well so little boat would be cool, but I think it will probably have more than 100 Hp on it. Those 65 hp boats look like fun but I dont think I could convince two friends to jump in a 8'-10' air boat. Everyone around here is used to the 9.9 hp on a 12' cartopper or we used 14' ers on the west coast saltchuck with 40 Hp. Thanks for the learning! By the way, still havent had a smoke!
