floor repair and exploration

I noticed the pylon cup in the bilge is slightly loose. I am unable to pry it loose with moderate pressure. Can I reinforce it by fiberglassing it to the hull?

Other than glass around it on the sides, how is it attached? Epoxyed to the hull?

I have all my foam poured and am about to get all my plywood glued down to the stringers and foam. I know...I'm one of those guys that decided to use plywood on top of foam.
I was planning on putting 3 layers of Biax over the plywood. Does that sound right? Too much?

Yes I've sealed it up with CPES. THX!

Teelta, I'm leaning towards pouring the foam after the floor is done. Just wondering how your process went, and if you had a lot of waste.

My thought is:
1) Install floor
2) drill strategic holes throughout the floor (every 3 feet or so)
3) Tip the boat on the trailer
4) Pour foam into holes
5) Cap holes
6) Glass floor

Did you let the foam expand and then cut it, or did you use something to stop it from expanding above your floor height?

Jeff, definitely without a doubt attach plywood, cut holes, and then foam. It will be a lot easier. If I had it to do all over again, which I probably won't because this floor should outlast me, I would foam after the plywood is in place. I used 3/4" in front section that covers the bulkhead and 1/2" the rest of the floor. Under the bow, I am fiberglassing right over the foam. I was going to cut holes in the plywood but when it came down to actually cutting the holes I thought it might weaken the plywood, which was stupid because the foam is dense and will support the plywood very well. I also wondered if the foam would fill all the voids if I had the plywood in already - there was no way of knowing. So what I ended up doing is pouring the foam between the stringers and ended up with a lot of waste. I ordered a 10lb 4lb. density kit and had to end up ordering more because I ran out. I did not enjoy getting the foam flush with the top of the stringers. It was not fun. Unless you have already gotten your foam, I would attach your plywood and use the injectable kind like Pete suggests. And if I remember correctly holes need to drilled every 18" or something like that. Also another advantage to putting in foam after the plywood is you are not cutting off the sealed film or skin that forms once it cures making it more impervious to water.
I don't know exactly what you mean by "cap holes" but you can just cut off the mushroom of foam that comes out the holes flush with the plywood and then fiberglass right over it.
Another concern I had after cutting off the mushroom is how do you seal the edge of the plywood hole? Maybe fiberglassing over the top will be enough, I don't know. But I guess you could cut the holes and then CPES the edges just to make sure.

floor exploration is a complementary maneuver for the treatment of zygomatic-maxillary compound fractures that permits the precise diagnostic of the lesion and the correct indication of repair.
