Let's pick your brains.

My wifes boat, Deb's Joy, is a 1968 century with a 160 Mercruiser. Yea, it's cool. The outdrive is a rebuild and I do not know it's history. I use magnesium annodes for cathodic protection but the outdrive still shows signs of corrosion.

There are loose white powder-like crusts here and there that I assume are aluminium oxide. Also the paint is coming off in places. I can see bare metal.

Any suggestions on how to stop this from happening? Sandblast, prime and paint? What products? Take it to a body shop? Gregorian chants?

Any thoughts would be welcome.
