View Full Version : Btm Paint Help--How Badly Have I Screwed Up?

To make a long and exasperating story short, I followed about a half dozen (local) recommendations to use Seahawk Biocop bottom paint on handybilly. Now I have learned that one should never use a copper-bearing paint on an outboard powered boat because of the increased galvanic action between the two metals.

By unexpectedly happy coincidence, I was in such a rush to splash handybilly and give my parents a ride since they were returning to the mainland the next day, that the bottom paint wasn't completely dry. As a result, much of it sloughed off where it was still wettest (probably 60% of wetted area). Hence, if knowledgable experts suggest I should scrape and redo with something else, I won't be heartbroken.

Humph. Thoughts, anyone?

I don't think there's a problem as long as you don't paint the aluminum lower unit with it.

It may erode the sacrificial zinc on the lower unit faster.

Anyone else have any knowledge about this? I'm hoping for a broad(er) concensus before I decide to re-do or not.

Thanks for the thoughts so far,
