Trying to do the math with the formula for prop pitch, but I don't have the gear ratio. Does someone have a quick reference chart? Its a 2001 90 HP 60* V-4 Looper. Right now I am guessing a 2:1 with an 11.1% Slip but I want to make sure since I need a new prop and wanna make sure I am right by just sticking with the 14 x 13 size thats on it. Thank You
