Hello all. I'm new here on this forum and I'll be in here a lot as i'm a first time boat owner... I have a 1969 Dorsett cuddy cabin w/ a 1968 volvo penta AQ130A motor (130hp). The current prop on there now is a 15" 15 P prop and the motor feels like it wants to go but somethings holdin it back...what would be a good size prop to go to? like a 15" 17 Pitch prop? The current prop has a chip or 2 in it so i gotta replace it....
