I've only had my Ariel (number 3 hundred something) for a couple of years, and it's the first sailboat I've ever owned. The engine is a 7 or 8 hp evinrude. The whole bottom end is about corroded away (the fins are almost gone) but the motor still runs fine. Also the engine doesn't seem to have a lot of effect when trying to back up.

Does anyone know how to repair or at lease stop the corrosion (I take it there should be an anode somewhere), and any advice on maybe a better engine, or something I'm doing wrong would be great.

Thanks
