KONA said:I maybe wrong, I was guessing by the part no. you have a enough horsepower to run a seventeen, you ideal wide open rpm is about 6000, i've always propped mine to run 5500
. I got a 20 ft pontoon with a 40 hp yamaha 2 stroke what can I do to get a little more out of it other than putting a bigger motor on it . I know its only gonna be a 15 mph boat but what will help the fuel milage or performance prop size / hydrofoil ??.Crusader said:James, chances are that the prop that came with the boat is just an "average" sized prop and not nessesarily set up for the boat and motor combo. Boat dealerships are known for not installing outboards at the proper height or with the correct prop for the motor and boat combo. I may not know much about big blocks but I do know boat, dealerships, propellers and outboard motors very well.

That's about all you can do. Time to put in a blown BBC in the center of the pontoon and direct drive. Then it will move.brazosjettin said:.

There's exceptions for everything.... Notice the "planing skegs" on the aft side of each pontoon? That's why that sucker can plane out.....
Mike 'toon.....well there's not much help for it.
