[QUOTE="Buddychrist, post: 280837, member: 9403"] Fresh water will not be any problem at all it doesn't have a reaction without salt. This is a saltwater problem that isn't 100% going to happen but it can. The salt starts electrolysis with aluminum being the anode which takes the corrosion. I'm talking long term here guys not like a year or two but many years of saltwater use. Why do you think they use galvanized U-bolts for aluminum boat trailers instead of SS? If you have an old trailer you'll see that the Galvanized bolts have a lot of corrosion and the aluminum is unharmed. Also another example is the Anode on your engine. It's there to take the corrosion of saltwater instead of the aluminum on your outboard. Here is a good review on how it works and some examples.
