Hi Ya'll... I need your expert advice. I have a 17.5' Seaswirl with a 90hp Evinrude. I need a kicker motor to troll and limp back to dock in case of 90hp failure. There's somone in town (small town) selling a 1985 Evinrude 7.5 hp motor. He says it runs perfectly. Comes with manual, extra tank and spare parts. Assuming he is right and it runs well...<br /><br />Q1: Will this motor be enough to troll a 17' boat?<br /><br />Q2: Are the 1985 7.5 motors any good?<br /><br />Thanks for the help!
