Re: Freshwater boat in saltwater prep
You need the proper anodes. Are they even zinc anymore? Doesn't matter; buy the recommended ones for your drive or any other parts that require them. Bravo in Salt = part numbers 1234, etc. I think when you order them or reference them it will mention the drive and the part numbers for whatever condition you run in. I have this mental note that we all call 'em zincs when zinc isn't even the anode material anymore (maybe I dreamed that).
If you want to spray some corrosion inhibitor all over the engine parts, there are some good/sticky ones that seem to last, but I don't know what this has to do with salt. I don't know how much of a must that is for anyone, but I guess the engine is most vulnerable to moisture in the air that tends to collect when the engine/boat are covered, so it's not really an issue of salt vs. fresh, it would be something you personally might want to do just because it's a boat. It's bound to get mixed reviews. Just look up 'marine corrosion inhibitor'. Some folks use wd-40. Some use nuttin'.
If you have a trailered boat, the trailer is on the fast track to being dust if it's painted. That's a tough combo. I suppose anything is overcome with more maintenance, but painted trailers and salt water usually result in very short-lived and expensive owner/trailer relationships!
