Bayliner 2452 leaking deck hatches-gctid350695

[Guest]

For some reason, I'm getting water leaking into both deck hatches (not the vents as I previously thought). The main problem with this is that on the port side, there is a slight hump under the deck - on the rear half under the deck water flows back and into the bilge, but on the front half, the water flows forward and settles against the firewall... and I just found out that this is causing some rot where some hoses go through the firewall as water just sits there and slowly seeps in. I can seal the areas where the water is puddling up, but this seems like a terrible design flaw to me!

-Has anyone had this problem, and is there a way to drain the forward portion of the under deck?

-How can water get in under those hatches (I confirmed it's not the vents, or rub rail)?

I recall having water getting into the cabin via that hose hole in the bulkhead. I filled around the hole with chalking and that fixed the water into the cabin... I know this is not what you asked but thought others may find this useful...

As far as the two hatches aft... I ended up installing thin rubber strips where the hatches sit on the inner hump around the opening that is suppose to allow water to travel in that area back to the scuppers. It never works that way but by installing the rubber gasket strips on that raised hump of the opening. It accomplished two things, it stopped water migration into the engine bay AND it stopped the annoying vibration noise the hatch covers made as they sat fiberglass hatch edge in the fiberglass valley. I also added more fiberglass and glass mesh to the underside of those hatches to strengthen and make them a tad heavier... (made for a better seal with the gasket strips...)...

That is probably the same hose hole where water was leaking on mine. This hole leads from the port hatch to behind the refrigerator... and inside this hole is a white hose, and inside the white hose is a smaller gray pvc hose. This pvc hose runs all the way from the refrigerator - to the port hatch area, then crosses over the the stbd hatch area. This hose was never connected to anything... what is it for? I thought it was a refrigerator drain, but it looks like the fridge is just supposed to drain directly down into the forward bidge via a big hole under it.

The best way to seal the deck hatches is to get some foam insulation tape from a local airconditiong supply house. This is a foam tape used to insulate refrigerant piping. Apply this to the underside of the hatch where it meets the lip of the hole in the deck.

If you put a small piece onthe underside of the button you lift the hatch with it will help seal there also.
