boat not getting up to speed
dear John, I just bought a 1986 regal ambassador 255 and ive been doing work to it .I have a problem with it getting up to speed.My fishing partner is a auto mechanic and has been helping me he says the motor is strong but we cant get it up to a cruising speed . It seems like the boat wants to go but doesnt . wondering if you had any suggestions for me . Right now it will get me where im going just slow. Thank you very much John.
Is the propeller pitched correctly?
