A prop that lets the engine run in its recommended WOT rpm range. What RPMs are you currently getting?

Without actual numbers there's nothing that can be recommended. You need a working and accurate tach and GPS speed

You can possibly borrow an induction tach from the auto parts store.

That close to the old Glastron hull....a 22 pitch will be real close if motor is in good shape..
