Replacing boat floor

Is it really necessary to use marine or treated wood to replace the floor.Would it be ok to use regular plywood and treat it with a sealer of some kind considering carpet will be glued down over it.The boat will not be left out in inclement weather.Also what is an easy way to replace floatation material,and with what.Just looking for some opinions,thanks.

If you haven't started this yet consider going to iboats.com and visit the restore section. You can read and see what many others are doing. Question I have is this a glass or aluminum boat? I am in the process of redoing my second boat. A 16' Alumacraft Classic. You can use marine ply if you like but it is not necessary. BCX or ACX woorks just fine and there is no differeance in the glue. The differeance is in the quality of the plies. The real secret is in sealing the plywood. Most use an epoxy resin, poly resin becomes brittle if used w/o cloth. On the Lund I redid 6 years ago I sealed it with 6 coats of marine spar varnish on both sides and 8 coats on all the edges. After 6 years it is still solid and still looks as good as the day I finished it. And tat was using BCX plywood from Home Depot. The carpet I bought thru Cabelas.

I have a'92 Mirro agressor 1625, and am considering changing it to a tiller. Anyone do this by themselves. I'd appreciate any input fellow L/L'ers. The lines of the boat don't seem dated to me at least.

i just used treated lumber but i roll on bedlinered the entire inside of the boat.

You"ll need to use marine grade because the glue holding the laminations together is different than on regular plywood. Separating from the bottom side is just as bad as the top. Marine is pricey but thats the way it is, I did it 6 yrs. ago and it is a job you don't want to do more than necessary.

Thanks for the input guys.

Marine grade always, treated lumber NEVER (if used on an aluminum boat)

I agree with Muskie Nut, if you're going to take the time to replace the floor, do it right and use marine grade. I would also use some type of glue, contact cement for carpet, and seal the floor with that when you replace the carpeting. Should be good to go for a long time.

I had a bad spot in my Tuffy after about 15 yrs. After peeling back the carpet I found out that they didn't seal just one of the holes that they use to inject flotation below the floor. It rotted out from there. I would use marine grade plywood, because I wouldn't want to to the job again in a few years. Its a small price to pay to have that last longer. I also sealed the new piece with resin as well. Do the job right the 1st time and be done with it.
