What preventative measures can I take to slow down the corrosive effects of saltwater against aluminum? I've got a new aluminum jet boat and I'm planning to do some limited time on the salt. I know that electrolysis is a major problem. Thanks for the advice.

First off, keep the zincs in good shape. You can treat the hull with either a wax or a more permantent coating like Sharkhide. When you're done, clean inside and out thoroughly with fresh water. A little soap will make the cleaning more complete.

Probably attached to the motor. It will be grey and appear replaceable by removing a couple screws or a small bracket.

It's also a good Idea to flush the motor or motors in fresh water soon after leaving the salt

Aluminum is more of a problem is it is left in for long periods of time- being moored in salt near electricity of some sort usually is the big problem. I will run mine down on day trips and not sweat it too much. Just wash her off when you get done and dunk the bearings a few times. Add some fresh grease and you should be good to go.

Remove any "stainless steel" such as tow hooks, snaps, bolts etc. From my experience that is the source of most problems.

I've decided to never moor my boat in the salt. Day trips are OK and follow the above advise. No problems.

I thought I was very good at maintaining my alum boat after it came out of salt water, which it fishes in about 80% of the time. I just got it out of the shop and got handed a pretty steep bill for repairs and replacement of heavily corroded parts.
I will now be even more vigilant about my wash downs and in getting lubricants in places I didn't know even exsisted.

Zincs are probably the most important part of maintaining your boat in salt water, seconded by a complete wash down with fresh water when it comes out.

I used ride waverunners out on the ocean at Pacific City. We found this stuff called I think called "salt away" it comes with an attachment for a garden hose. Anyway, you spray down your boat with this stuff and it supposedly neutralizes the salt. I use it in the engine bay as well and NEVER had any corrosion and I used to get water in the engine bay all the time

add more zinc !!!!

you can buy various shapes and sizes and either weld or bolt them to the boat (weld is better). I have a chunk the size of a big dinner steak welded on near the transducer, wouldnt hurt to add another one or two.

Be VERY Carefull not to have ANY copper on your boat. If someone drops a peeny on the deck and it goes un noticed..It will eat a hole through your boat

I heard you show spray and whipe the hull surface with WW40? Just what I heard for bare alum. Mine is painted and I just wash and wax.
