We at Hill Marine, like small boats as well as big boats. Would you interested in showing us more pictures of your boat, like a front and back view? Which Hill Marine 50 HP Yamaha, 13 spline propeller do you have? How much does your boat, motor and driver weigh? About what speed are you getting? How many lap races do you usually run? How many races each year?

This boat looks like it is sitting well on the water...Sure looks like a fun boat to drive...

Thanks for posting!

Ron,
Total weight was 220kg, manage to go 71mph, race course about 1km long, 10 laps for 50hp 8 laps for 30hp

prop 13 spline 12 x 20.5, 3 blades with no through hub, hoping that i can improve accelaration to midrange with less surface on current prop or with 4 blades smaller diameter n same pitch.

This looks like a lot more fun than my little fishing boat. Maybe I should get rid of it and build up my little Yammie 50 for speed instead!! Nice!

Nice looking boat, it certainly sits up well.
Have you calculated the prop slip with the 12x 20.5pitch clever? Or is it a chopper prop ?
Also what RPM are you pulling?
