leaky hatch gaskets.

My Endeavour 40 (1981 cc) probably still has the original gaskets. I have tried numerous types of self-sticking gaskets but cannot seem to stop the leaking. The problem is the uneven surface that the gasket fits into on the hatch. Does anyone know where I can find original equipment replacements or a good substitute.

Not sure if it will help in your situation but try rubbing a bit of Vaseline on the gaskets. It stopped the leaks on a couple catamaran escape hatches I delivered.

Vaseline over a period of time will degrade rubber and variety of rubber like petroleum based products. It does work well short term though. Food grade silicone grease is probably the preferred choice. It is available at plumbing shops, used for lubing faucet cartridges amongst other things.

I have a Contest 31 with seriously leaking gaskets. After cleaning out all the junk the Previous Owner used that did not work, I applied this self-sticking gasket. The gasket is sold by the foot but you need to get the right size gasket and take the time to wedge it into the hatch properly.

9/16" gasket
Note: Gasket is sold by the foot.

Good luck,
George

Leaking hatches:
Test by chalking the Knife edge all the way around the hatch and then close and dog it. Open the hatch and check the gasket. It should show an unbroken chalk line all the way around. And if not? Then you may have to do the following.

1. Check the edge that the gasket comes up against. Is it straight and square to the gasket? Have seen some knife edges bent, concaved, convexed and wavy. And there was no way that a good gasket could get a water tight seal on those edges.
2. To fix mis-alined edges you may have to file, hammer, adjust hinges and/or dogs, or force that edge into alinement, rebed or replace the whole unit.

Chalk testing your gaskets quarterly/seasonally is good preventive maintenance. The chalk? From your kids' toy box or get one that is made for the task.

Thanks for all the great ideas. I will try and find the name of my hatches, but I think I tried this awhile back and couldn't find any identification. The chalk idea sounds like a good way to go. Maybe then I can try and use the self sticking gasket material I have now and then re-chalk and see where I stand. Thanks alot and am really glad I found this site.

one other thing: If you deck is warpped that may twist your hatch and throw it totally out of alinement. You may have to rebed that hatch and be sure that the bedding is square and the hatch is square also.
