What are the best screws to use for remounting a wooden transom to an aluminum jon boat?

Question

It has huge 1/4 x1 1/2 rivets in it now and i can't find them anywhere. I was wondering what to use instead and if i used regular bolts what kind of sealant to use. Thanks.

Answer 1

Swampman, go to Lowes and in the hardware department, get stainless steel screws 1/4 inch. I would use GE Silicon sealant. Make darn sure that the area you are going to seal is clean and dry, and give it an entire day to set up before doing anything with it.

Answer 2

Aluminium and stainless, not a good match.

If you want this to be a long term fix and stainless is the only fastening you can get, I would suggest you have a nylon insert and washer where the stainless bolts would make contact with the aluminium.

Yes, 5200 is a ideal sealant and if you use "5200 rapid cure" it will go off over night.

Answer 3

I'll try to remember to ask a few people tomorrow at work.

I'm not sure if it's wise to have stainless and aluminum together for long periods of time. They might react together in a negative way over time. I could be wrong, but I seem to remember something about this.

I would guess that silicon bronze might be good, but it's very expensive.

If you want to do a permanent repair, use 5200 as a bedding compound. It takes a full week to cure, but it will be PERMANENT. I mean PERMANENT!

Did I mention that it would be PERMANENT!

Not kidding.
