I'm running a 17 x 44 Southfork Mud Hull. My motor is a mudbuddy 25 hp but should be pretty close to the same results as you.

I have heads, exhaust and carb and I run 27 mph with 2 men, dog and hunting load with my big blade prop. When I put my 9" diameter prop on, I drop to 21 mph because I have to keep the rpms low enough to not hit the rev limiter.

B Schwartz, get some cup and pitch added to that 9" prop. Let the engine run where it wants to and let the prop keep your rpms where they need to be.

It's currently pitched to a 14. I will look at having some more cup put into it after the season ends.

I have even thought about getting a 3 blade and having it cut down to a 9" diameter and having it worked to see if that will give me a better range of performance.
