I just had an interesting experience. While running a NMEA2k network I bumped my through hull fitting from the bilge pump which promptly snapped off. Inspection showed the plastic, I'm assuming nylon, to be brittle. There is no way in this world that I want any through hull fitting to deteriorate. Its simply a ticking time bomb. I also have similar fitting below the water line for livewell intake and drain. My intent is to carefully cork them wet with 4200 until later when I can have the holes plugged with an aluminum patch. I did not see any signs of deterioration on them but why take chances? I would rather install a different pump that pulls up above the water line than have anything that could sink the boat.
The root question: Is Marelon or other plastic fittings going to be as strong 10 years later? I need something that will be as good going forward as the day its installed. How about Stainless with Tef-gel? I have been using the tef-gel and rubber washers / gaskets on all of my other connections. I did not find much with a search here. If I find something on Google I'll update but would sure appreciate anyones experience.
