I have a 1977 25 horse johnson.<br />14 foot glass runabout<br />5500 WOT.<br />Doelfin hydrofoils<br /><br />Prop is aluminum Michigan Wheel prop with the numbers 012013 stamped on it. It is roughly 9 inches in diameter. Any guesses on what the pitch is if I try to replace it. The motor seems to like the prop and I would like to duplicate it exactly.<br /><br />thanks <br />Jim
