I have a 26 foot cabin cruiser and others with same boat are getting 12 MPH top speed.
I think I may need to change prop size . Is there a special way to find out what pitch I need?

12 mph the hull isn't even on a plain so there is other issues>??Should be 20+ mph if a plaining hull>>Here is the way you can tell> Does your boat at wide open with a load reach manufactures RPM if low than decrease prop pitch> If over than increase the cut size for 200 RPM if more needed than go up 1 size in pitch>??

the motor manufacturer manual will give a recommended siz and pitch for your load condition. you may have one for heavy load and not speed. less pitch may give you more speed. your boat hull design may also affect speed. mercruiser.com has a lot of good data to help you select the correct prop.
