A word of caution...
When you launch, before you release the boat, but after it's in the water far enough for the through hulls to be submerged, get on board and check each one for leaks. Even the pro's do this.

Good luck!

Different Experience

While others state that they have no issue with Marelon Seacocks, I had nothing put problems with mine. The PO had one on the boat and did it as a stop gap. It was for the engine intake and was fitted to a bronze thru-hull strainer. He wanted to put anothter bronze seack, put heard good things about no corrosion, easy to operate, etc. that he decided to go witha Marelon vale. We had the boat almost 2 months and made a practice of closing the engine intake after every sail, so it was exercised weekly. Around two months into it's life, I had a hard time moving the handle and finally got it to rotate. Thinking it was now operating fine, I continued the rest of the season moving the handle back and forth (open/close).

At the haul, I started to take it aper to grease it, as you should.. Found out that I had actually sheared the hadle and all I was doing was rotating it back and forth. The ball part wasn't even moving. It was locked in the Open position. Replaced it again and made sure I religiously greased it throughout the season, by closing the valve, removing the hose to the internal sea strainer, and putting so waterproof grease on the closed ball surface. Even doing that, I managed to shear the plastic again at the end of the season.

Mentioned it to the PO and he said he had that happen to him several times in one season. Had he had the time, he would have put a proper bronze seacock

This year I swapped out the Marelon one for a true bronze one. For critical applications (below wateline), I will never use a plastic assemble again.

Unhappy another broken handle

I broke the handle off a Marelon seacock on the WC water intake line in a '94 Marshall 22 last weekend, trying to turn the valve to the shut position. I wasn't putting much pressure on it when it broke off. I don't know when the seacock was last serviced. (The boat has been mine for only three weeks.)

through hull removal

The best way to remove the old thru hull fitting is, (for 3/4 inch fitting which they probably are) use a one inch twist drill bit from outside the hull and drill up into the hole till you start to see fiberglass then the mushroom end will fall off and you just go inside and pull the rest out. should take 15 to 20 minutes per fitting complete.
