    electrolysis is the thing that eats them. cleaning the boat and flushing the motor after use helps. look for signs of corrosion clean and paint spots, any bear metal will cause trouble.

    Don't forget your boat trailer. It will need a good cleaning after a dip in the salt water. It can be bad on tube type frames that water can enter. Even galvanized dipped ones can get eat up over time. I know this from experience , my son had my previous aluminum boat in FL for about a year and half. The boat held up well. The trailer had some corrosion on inside of tubes.

    I don't know the answer, especially since the great lakes where I fish with my boat is unsalted and shark free.....but them boys along the Atlantic all have fiberglass boats for a reason I would think.

    I fish the brackish marshes of South LA regular and have both Aluminum Crappie boat and Fiberglass Center Console that I use. Electrical connection corrosion will be your problem. The salt in the air affects them. My Center Console is designed with electrical connections sealed and has no problems. Aluminum boat has open spade connections and is always trouble. Keep you a can of contact cleaner!!

    I bought a used boat from NY. It had some salt water time, but mostly fresh water. It's a Starcraft, hundreds of rivets.
    About half the boat's rivets had corrosion, as did that same part of the hull. The former owner said he always washed, and never left it overnight in salt water.
    I was able to sand /water blast, and seal all the rivets and bottom. Expect it to last many years.
    I was told that had the former owner painted / sealed the entire boat, no corrosion would have happened.
    Unpainted, in sealed aluminum begins to corrode immediately when in salt water, I was told, by a retired marina owner from Maryland.

    Exactly what i've experienced in my only occasional SW usage= GALVANIC CORROSION. My highly-polished SS hatch-hinges(8) are aluminum-rivet attached. The softer metal(aluminum) rivets are being attacked due to their incompatible metal chemistry. ALL rivets need to be drilled out and refit with SS rivets. Contacted manufacturer about 3 months ago and got an "I'll discuss with the Owner" response...still waiting, but still having a BLAST w/my newest(last),lol rig!
    Thanks for checkin' on me! CURIOSITY takes me there, SUCCESS ushers me back!

    Cheap steel trailers might help to flush salt out of them . Seen them rust into after being in salt water
