Vent on scepter, water in gas
 
I am consistantly picking up alot of water in my gas. All the obvious things appear to
be fine. Heres is the deal:
The vent on my boat is mounted on the side of the hull and is facing down. When I
run with the trim tabs down, water really flies up the side of the hull, and maybe is
entering thru the vent. Anyone have and ideas or experiances simular to this?

JOHN B:
My gas vent is is about half way down the lenght of the boat 4" below the rail. Pointed to the stern. no water. how are you getting water from your t. tabs[stren] going to the side of the boat? or did I read that wrong?

Point the vent aft and slightly down so no rain/wash water can get in and you should be able to eliminate the vent as a source of water in the fuel. [img]images/icons/grin.gif[/img]

Thanks for the replies. On furthur inspection, the vent has 2
holes in it, 1 at 3 oclock and one at 6 oclock (bad position).
I thought about just 5200'ing the 6 oclock one shut, and
leaving the 3 oclock one there. When I have the nose of
that thing down, the water comes up the sides when I hit
waves. If you see the other post, I am getting a fair amount
of water in the cabin from water coming up the sides thru
some gaps underneath the rub rail. Maybe I am running
the nose to far down, but when I do, it really smooths out
the ride.

Don't plug the vent you won't be able to fill the tank or get fuel from it!Try getting a clamshell type vent or putting a clamshell over the existing vent.

Hey John

All I can say is that on mine the vent is about six inches under the rub rail and is angled back so even if water were to run up the side of the hull it would deflect from the vent .... unless somehow there was a vacuum in the tank.

If yours is pointing straight down maybe its scooping up water as its forced past the vent... Just a thought. It should be easy enough to angle the vent to the aft of the boat.

You sure your not getting water in the courtesy of your fuel dock/gas station?? [img]images/icons/confused.gif[/img]

Hope you get resolve to the problem quickly !!!!!

As HermCo says replace that with a "clam shell" style and point it at 4 o'clock. I would personally stay away from trying to "improve the design" of the one you currently have. Thats looking for bigger trouble in my eyes

Forgot to say that the vent hose should have a loop before the vent or at least be run above the vent then down to it to prevent water intrusion.

Had the same problem with my 1986 23' walkaround, so I replaced the vent with a new model two years ago and problem gone. I can not remember the name but it's made of black nylon and has baffles to stop water ingestion.

I am curious as to what you did about the rub rail problem, I too am getting water in my cabin on the port side and cannot visualize any seams or cracks or any portals of water entry. It only happens when Im cruising in following seas and I bury the bow into (not thru) a wave. I have the identical boat except mine is a 1979 and no hardtop. Is that a 250hp on there? Mark

All,
The vent problem appears to be fixed. The vent had a 90 degree elbow in it facing straight down and there was no loop in the hose. This kind of acted like a siphon. Good think I have 2 water seperators in line. I put a 6 inch loop in the hose above the vent and water will have to flow thru the 3/16 inch vent hole, and then uphill 5 inches to get headed to the tank. This should cure it.
MarkDPM, check out my post on leaking rubrail seam. I am pulling it off tomorrow, and resealing it with 5200. I will post back the results. I was have the same problem, only on both sides of the cabin, and even running in by the cockpit seats underneath.
