hello all Purchased a 1990 Glassport 18' a year ago. Has a 3.0 murcruiser, and alpha one out drive. Everything mechanical works great. I have started to notice some floor rot, and the seats are starting to crack. I have no problems fixing the boat floor. I just dont want to get in over my head money wise. Doest anyone have a rough estimate on what kind of money Im looking at on worst case senerio for entire floor replacement. I also dont find much info on this kind of boat any experts out there. I belive the manuf. was Waitburo. I have been reading these forums for awhile now one of my favorite past times.
