Good evening all. JFKSail reported problems with rotten plywood core surrounding his portlights. I too had discovered damage on my L25 after removing them, especially the center ones.
What I did was take and angle drill and remove the plywood core about 1 3/4" all the way around the portlight. This takes about an hour per window.
I then used the waterproof epoxy paste (1 hour curing time) from Home Depot to fill in the void. The technique I found that works best is to cut the paste a little with acetone and work the paste in using a pair of tongue depressors sandwiched together and dipped in acetone. It takes about 16 oz of epoxy to fill the void per window.
BTW... I used this technique on the Beckson PF714 (7"x14"x2"). My core is still solid surrounding the PF310 (3"x10"x1.25") and if required I haven't figured out how to get the drill bit into that small space. Suggestions welcome.
