Advice I got...
was from a Hunter employee named Al Fookes, you might ask for him at 800-771-5556. I was lucky enough to find an ex-Hunter dealer in my area who employed a lady who had experience in replacing the fixed ports you are dealing with. I was out of town when she did both port side ports on my 35.5 and didn't get to watch. Here are some things I remember from research: 1)once old port is removed (piano wire or guitar string works best) the opening MUST be ABSOLUTELY clean of all traces of old adhesive. 2) Before applying new sealer, mask off around the outside of the opening very close to edges with blue painters tape. 3) You MUST use the correct Dow product, I believe it is #795, make sure it's "fresh" as it has expiration date. NO other product will hold up. 4)they cut some pieces of 2x4 and made braces off the lifelines and stantions that held the ports in while the Dow product set up. 5)the LONGER the boat can sit without being used, the better the repair will be. Premature flexing of the cabin may make the ports pop out. Wish I had been there to watch...that's about all I can offer. You can buy the ports and Dow product direct from Hunter.
