aluminum hulls

[wrenier]

I recently aquired a lund genmar 2450 for extremely cheap..everything is in good shape execpt the transom, it needs redone..my only question is once the transom is done what else can go wrong with the aluminum hull? rivets are all good and no leaks whatsoever.

Not much unless you run in saltwater a lot in which case corrosion COULD become an issue.

An application of Gluvit to your rivets and seams is good insurance against future leaks.

Re: aluminum hulls

The place doing the transom said they want to use double laminated marine grade plywood. Is this the best option for the money? Thanks

Won't get much better than that! You'd still want to seal it though. Contrary to popular belief, marine grade plywood is not treated against rot. It's just a higher quality product.

+1 on the plywood! Have the business coat the new transom in at least one thick coat of fiberglass resin, just resin. Alot of people are doing wild things to their "tinnies." Go to www.tinboats.net and check them out. Its well worth the look. Oh! welcome to iboats!!!!!!

Not quite correct. It needs to be EPOXY resin. Polyester resin (which is less expensive and is what I think of when the more generic term of "fiberglass resin" is used) is useless by itself without fiberglass. It will crack and peel in short order.

Best way to seal a transom board is fiberglass (with either poly or epoxy resin)
2nd best is epoxy resin alone (any parts exposed to the sun should be painted as epoxy doesn't like UV)
3rd would be something like marine spar varnish
4th would be anything else like paint, polyurethane, etc etc.

and goboating, I'm sure tinboats is a great site but I'd rather not send ALL our aluminum boat owners over there. I think we have a pretty good community here that myself and a lot of others have put a lot of effort into building.
