Another thing that has not been mentioned that you need to take into consideration is the rpm's of your engine. Change in prop size/ and/or pitch changes rpm's of motor. KNOW your motor's maximum rpm. It's not the red line! They vary from one motor to another, not hard to find out though. I believe it's ok to get a prop that will exceed your motors rpm, just don't do it. You may want to confirm that for peace of mind though. I wouldn't even put a prop on my boat that exceeds the maximum rpm's if you have multiple drivers. Someone WILL forget, and blow the motor, just a matter of time. You don't want to have to put in a new motor to go with your new prop... (unless the other driver's are paying for it!!) Sometimes you will lose rpm's in which case you have no worries.
