95 maxum outboard

[ricardo.benin]

Hi I have a 95 maxum it is a bow rider and it has a 120hp force outboard any ways on the port side rear quarter underneath the rear side seat were the little door is that the battery is behind there is a little spongy spot that has got me worried so I was wondering if anyone has had this problem and knows how to fix the problem basically it seems like there is like a piece of ply wood that is rotted out but the thing is that it seems like it is at least 5x6 but when I took a look at it seems like when the boat was made that they forgot to glass it in and put a piece of plywood to cover hole. Any help would be greatly appreciated.
Thanks

ricardo.benin welcome aboard

maxum like most boat builders use marine grade plywood and then glue the carpet directly to it without glassing the plywood or just put down 1 layer of mat glass. It is rather common for this age of boat to develop soft spots whether the plywood has been glassed or not. The bad area will need to be removed and replaced.

Ok basically I was really worried about stringers. Do you know if they are glassed or not.
Thanks

The stringers should be glassed, however these can also suffer from rot under the right conditions. The decking is screwed to them and may result with water entry, cracks in the glass can form understress if the radius was too tight where it bonds to the hull, ...

[ricardo.benin]

If the stringers are in fact glassed I should have no problem as the rot is not near the stringers but it is weird because when I press on the spongy spot there is like a sharp lip that seems to be marine ply wood so my guess is the spongy part is regular ply wood. Forgot to mention but the spongy spot seems to be a little triangular piece but I will just tear up rug and have a look.

Let us know what you find and post a picture or so if you can.

[ricardo.benin]

Ok I will but it is looking like I can get t it by weekend.
Thanks

Got to the rot today and I think my floor supports will be ok and I found out that there was a hole under the rug were maxum put a hose in floor hole to put the spray foam in and the little battery cover door that has a hinge has rot were the 4 screws went through floor to hold the door hinge in place. If you see or know any thing else I should check please tell me what to do as well as how to go about the fix of the floor.
Thanks

Check the foam to ensure it is not holding water which will lend itself to further rot.

[ricardo.benin]

The foam is holding water so should I remove it and re foam.
Thanks

[mmwjr]

I recommend remove and replace the foam.

[ricardo.benin]

What foam would you use and I believe that it has to be gasoline proof but I noticed when I tore out rot that the bottom layer or two were mostly good wood in the ply but it was the top layers that were rotten.
Thanks

I knew you would ask this question

To be honest I don't know what foam to use. Frankly not may folks at this site perform this type of work. I recommend you visit the BOC (Bayliner Owners Club) site and ask there as a fair amount of them have done surch and much greater rebuilds. Good group of folks.
