Auctioned FWC airboat?

[Prototype]

Seen a former FWC airboat at auction and the poly was visible through the alum hull?

How the hell does that happen? Wrong alloy with salt water in it for years??

Some herbicides will do that if left to sit and not rinsed off.

If you put an aluminum boat on a salt water soaked, carpeted, pressure treated wood surface it can do that! Have seen it before where some sort of current builds and electrolysis causes erosion.

Crazy.... always have the plastic bunk covers for a aluminum hull saltwater boat.

we bought an auctioned swift-mud airboat a few years back. when cleaned up, the floor was really bad in spots. we cut out the spots and welded in patches. luckily the corrosion was not under the runners. made a fine boat.

What does the inside have to do with the bunks? The bolts maybe?

i wonder if zincs would help. i have always put them on my boat.

Zincs will help with galvanic corrosion but not with chemical degradation. I fixed a neighbors aluminum jon boat that had a corroded area caused by a bag of fertilizer left in the bow. If you're considering buying the boat and the damage is caused by galvanic corrosion from salt water, the damage could be extensive…all the area that was exposed to the salt water electrolyte could be affected. It may still be a good deal if the rest of the hull and engine are good…and the price is right.
