Boat floor replacement

[MuskyRookie]

I am looking for the best type of wood to replace my boat floor. Is there marine grade lumber available for this?

there is marine grade plywood, but it runs around $100 per sheet. . . Try posting this in the "boats & motors" forum, there was a discussion about this a month or two back. I think the guy went with regular plywood & wood and got a good marine grade lacquer/sealer. Sikkens makes a good marine sealer.

I think menards and homo creepo have to order it in.

SUPPORT YOU LOCAL LUMBERYARD! NOT THE BIG BOX!

i wouldnt use marine grade. i would just get some treated plywood. alot cheaper and i suppose you could put some exterior paint on it also to make it last longer.

After doing two boats and a pontoon, I highly recommend using true marine plywood, yes with the higher cost, as it works best. Look up the other post for my reasons, and for other's reason for why they went with what they did.

Good luck, it will be a cool project, I just recommend doing it right the first time. My first time I did not... wish I had

Most of the treated plywood at the retail level is highly corrosive to aluminum. Thats why on decks you need spacers between green treat and aluminum siding or aluminum balisters. Better to use marine grade or exterior plywood with good sealer on it.

I'd vote for CDX plywood (exterior rated glue) and Sikkens marine grate cetol sealer. that will be less than half the price of Marine grade and if you use common sense (keep it covered when possible, let it dry out if wet) should last you quite a few years.
