Trying to figure out my prop slippage and am wondering what the gear ratio would be on a 1981 Evinrude 115hp.<br /><br />I'm thinking I remember it being 2:1 but am not sure.<br /><br />Have had the boat out once this year and it ran perfectly with WOT at 6,000 rpm. Forgot the GPS so I'm not sure the speed but am going out tomorrow and just want to see what the slip seems to be.<br /><br />I have the sites for the slip % so just need to confirm the gear ratio.<br /><br /><br />Edit to add: Found it. http://www.piranha.com/motor_specs.php?id=6924 <br /><br />I was right at 2:1
