Takes a wrench and about 30 minutes to get it out, so it stays in the water always. The spray antifouling available for outdrives is pretty much worthless. Used to use TBT but that's not available any longer.

Question is this. What if next time I yank it out, I coat the leg and prop with a heavy coating of Coal Tar epoxy ( the stuff used to protect iron platforms and buoys) and then apply a regular copper based bottom paint (which DOES work well) over that.

Do you think the epoxy would isolate the aluminum enough from the copper, to stave off electrolysis?? Or should I continue to spend several days twice a year to scrub, sand and respray with the crap available?

Ideas?
