Pitting on aluminum

Duckworth1 · #1 March 2nd, 2005, 10:51 AM

I noticed some small pitting on my aluminum boat, not bad and it can be removed by scratching it with a finger nail. Since I haven't noticed before, I'm assuming it is just starting to pit.

I have zinc plates on my outboards and was told that was all I needed to keep the aluminum on the boat from corroding.

Any ideas what I can do to stop it while it is small? What treatment can I give the boat as a preventative?

Duck it sounds like the boat is bare aluminum,is that correct????And there should also be a zinc on the hull.Charlie

Crazy Charlie is right. Your boat needs zincs even if you trailer your boat. If you do trailer it helps if you rinse the boat with fresh water.

I've found Paint Also Helps......
