Re: Std Prop Pitch - 1989 17' Capri w/ Force 85 ??
...I'm a little new to this but I think its either a 13"x15pitch or a 13-1/2"x15 pitch.
I stopped by my Mercury/Force dealer the other day and he had a great pamphlet on propellers from Mercury showing the whole lingo.
The first number reference in the propeller term is the diameter of the prop and the second number is the theoretical distance the prop moves in one rotation. In this case it moves 15" forward.
This is just the basics.
Then there is skew, rake, cup, slip, ventilation specs, 4 blade vs 3 blade, Stainless vs. aluminum...etc. It appears to be quite a science however I know squat about that stuff at this point.
Check out a local Merc/Force dealer and see if you can find this pamphlet....its pretty informative.
Good Luck
