55.1 mph with 30 hp mercury
I finally broke 55 mph in my racing flat bottom. I bought a mercury chopper 2 18 p and this prop is amazing. I know you guys think i might be crazy but my motor is to low in the water for running a chopper. My prop shaft is 2 and a half inches below the bottom of the boat and i still have some rpms to play with before i hit my rev limiter. How much more speed can i expect if i continue to raise my motor??
Looks Real Good for a 2 Cylinder
What I would do is, put a nose cone on it and raise the motor up till the center of the prop shaft is level with the bottom of the boat and you will see more top end. Also a good 6 inch jack plate will help and unlpug that rev limiter, you did say ''race boat'' . But I dont know how u race, in a cicle or drag? I dont know nothing bout going in a cirlce.
