Replacing floor in 22' Crownline

[wingman65]

Hey guys, this is my first post but I've spent a couple days digesting the wealth of knowledge here. A friend of mine recently bought a '94 Crownline bowrider that has been exposed to the elements for years. the upholstery is shot and the floor has some soft spots. I'm going to help him refurbish it starting with a new floor as I have decent carpentry skills and tools but have never repaired a boat floor before. What did I get myself into???

How well were these boats constructed or can I expect a nightmare revealed when the floor is removed?

What kind of wood was used on these and were they sealed with epoxy or polyester resins? If Poly, can I epoxy over the old poly and how can I tell which resin was used?

Can I just cut out the bad wood or should I cut it all out and start all over, and what type of ply should I use when carpeting over it? Is there an issue with carpet glue adhering to epoxy?

Sorry for all the questions, I feel I have the ability to do the job as long as I can aquire the correct information.

Thanks

Tony

Thanks for all the help guys, I guess you guys don't like Crownlines:confused:

I found enough info on this and other forums to proceed with decent results. I used 3/4" HDO ply for everything and I believe the boat is more solid than ever. Everything was sealed with epoxy.

Great work. I don't use HDO because I was told it has a coating to allow it to be used and re-used for concrete forming, the concrete doesn't stick to it. I assumed it would have adhesion problems, but I certainly don't know that, never having used it. I have used several tons of MDO, Olympic Signal grade, really great stuff. If HDO is as good as MDO you will have a floor that will last a very long time.
