    Well, as most of you know, I have years of experience of working on salt water motors. And I am going to possibly raise a howl here, but I am going to say that NOTHING will prevent fastener corrosion in aluminum in salt water. But the OMC Gasket seal does help, and I routinely used it. BTW, OMC did use it back in the day. OMC’s Anti-Corrosion lube (grease) is great stuff too. asa, you suggested an anaerobic thread sealant. That is great stuff (Locktite blue) and works in the area of actual thread engagement. But it would be difficult and expensive to try to fill the complete fastener length/hole. Besides, the hole generally is considerably larger than the bolt, too much gap for the sealant to work.

    I had a customer that worked for FPL, and every time he brought his motor in for any service, he brought along a tube of greasy stuff that they used on power lines. He swore up and down that it prevented corrosion of the wire connections, even out along the beach. And it did help, I guess, on his motor. But 100% guaranteed satisfaction? Did I mention "nothing"?

    There is something that helps tremendously: Never put it in salt water. If you do, wash and flush. But don’t kid yourself, the flushing isn’t going to get in the bolt holes.
