Portlights

[joemondi]

does anyone know the thickness of fiberglass at the portlights for1988 aquasport 29 foot im replacing them with stainless portlights

No.

But easy way to find out is to remove one and measure. Can then either pop the portlight back in or simply gaffa tape up the hole.

That area of the boat is not that thick because they need to keep the boat light. You will probably see 3/16 to 1/4"

You really should not have a problem as most all ports install by bolting the inside to the outside. The bolts just hold the port while the caulk sets up and don't really do much more. The difference between the expansion coefficients of the fiberglass and the metal plus the flexing of the boat requires the ports to flex just a little bit inside the hole. The caulk is what prevents the leaks and allows them to last a long time without leaking.
