Hi There,<br /><br />I'm trying to find out what pitch propeller I can put on my 1972 Johnson Sea Horse.<br /><br />The model number is : 20R72R<br />The Serial number is : C43468<br /><br />I'm looking for that information because I feel that I lack a bit of power. I use this engine on a 14' fiberglass boat, the boat is very heavy.<br /><br />I looked on the propeller I have on it (was there when I purchased the engine) & it says : 012011..<br /><br />I'm not certain if the pitch is 12 or 11 on it..!!??<br /><br />Any help will be greatly welcomed.
