I painted the motor so I wouldnt have to look at that salt oxidation that I have been swearing at so long. I used a wire brush drill fitting and removed most of the corrosion with no problem. Shiney metal is what I like to see. 500 degree engine paint in semi-gloss worked well.....even though people will never see the motor...Notice the Alternator...still the old Paris-Rone unit that is BAD. Its been tested and that is confirmed. I'm having trouble locating a replacement for less than $300.00. If any one of you reads this, (if anyone does), you can find me on Iboats.com and I will be all ears!!!
