I use scotchbrite pads on an air powered die-grinder to prep the exposed metal/corrosion, light sanding over the old paint. Zinc chromate the exposed metal, and then coat everything with black engine enamel.

Lots of good stuff here but a couple more ideas, after you blast or sand you must Zinc Chromate right away because the case will start to oxidize immediately. Use a good epoxy primer, key word being epoxy. If you need to use filler shoot primer first then prime over. when you shoot the Zinc Chromate go with a very light coat, you are using it as an etch not a coat. Do not skimp by the good stuff or you will do this next year to.

I did mine 5 years ago cleaned it up sanded rough spots and sprayed it with rustoleam gloss black Still looks ok and touch ups are simple. The boat is on a lift so it isnt in the water all the time
