Re: Saltwater guys: Out Drive spray paint is worthless.....do NOT waste your money.
You keep an outdrive in salt water??? I think the least of your problems is going to be green stuff.
Uh-oh. I guess I'd better replace my 14-year-old drives right now, and warn my friend with his 1992 Larson to do the same. The guy at my dock with the 1983 Mark Twain and Merc drive is probably about to sink, too. Thanks for the warning!
Okay, I'm funning with you, but comments like these either annoy me or make me laugh (depends on my mood). None of these boats has any corrosion or operating issues, and none receives any more than routine annual maintenance, new zincs and anti-fouling paint.
As for the OP's post, I agree that the spray stuff is crap. In these waters it's barnacles and spray paint doesn't cut it. My marina uses Aquaguard (brush-on) paint on the outdrives and tabs. Several people have told me it works great... I don't know yet. I'll probably get into the water this weekend to inspect and scrape whatever's on them. I can tell you there's plenty of green slime, but that's pretty normal. A scotchbrite pad will clean it right off.
