I yanked my plastic one out in '05 and replaced with a SS threaded Gem thru hull with the nut in the fish box sealed with 5200
I keep a semi-yearly eye on it to ensure NO Water intrusion! Still good to go.

BTW: Measure first, then cut the tube to fit. It would be difficult to trim it once in place. It will take two people. One to hold the flange outside in place while person 2 tightens the nut inside the fish box.

Thanks Chuck I was thinking the exact same thing with the Gem 3/4" x 6 1/4" threaded thru hul BUT was wondering if I need to re-enforce between the hull and the liner to create a solid base for screwing it tight withuot flexing the skins too much.
