[QUOTE="atuck593, post: 189676, member: 4904"] Nice build you got there... From what I have read on here the treated plywood is a no go because the chemicals used to make the plywood water resistant react with the aluminum. Over time as the chemicals come out of the plywood they will corrode the aluminum on your boat. I have also read the same about galvanized bolts and brackets for any deck framing. I am not sure how long it will take to cause serious damage to your boat ( a few months...a few years...a few decades) but the general rule of thumb on here is to not use it. A few days ago threre was a post about a new type of outdoor grade plywood that has new chemicals. Apparently it won't corrode the aluminum as severly or as quickly. You could search that thread to see what came of it. It's only a few days old. The best advice from my limited experience with this would be to check up on a few builds from guys who have used pressure treated and see what they have done and how will it has worked for them over a few seasons. If it was me I would just use the pressure treated as a template and then use the good stuff. It would only cost ya a piece or two of plywood. I would hate to have invested the time money and energy only to have it cause damage to the boat itself and create more work for me later on down the road. Hope this helps ya out with your question about the treated lumber. [/QUOTE]
