Hello,<br /> I am looking to replace the prop on my 1988 15 HP Johnson motor. I am using the stock 9.5 X 10 one right now. It is on a Grumman Semi V Bass boat (around 700lbs loaded with gear). I was wondering if anybody has replaced there prop on there 15HP motor to a replacement prop and upgraded to maybe a stainless one (yes they make one) or a new Hustler brand prop for underpowered boats. Would it be worth the time/money for the better performance you would get maybe. Any help would be appricated. <br /><br />------------------<br />Scott
