Carver Owners Forum

Hello All,

My boat is currently moored in the water and I've noticed that she seems to get 2 to 3 Gallons of water into the mid bilge area on a 24 hour period. This is the centreline bilge in the Engine Compartment and there are forward and Aft limber holes for water to flow forward and aft to the other bilges. I've done extensive investigation and ruled out the aft thruhulls, the rudders, the waste and fresh water tanks (all empty), the shaft packing don't leak at all and the raw water intake thruhulls for the heads aren't leaking, nor are the discharge pump.

The boat is in brackish water in the Fraser River in Vancouver and although there have been many days where it's been dry the water is still finding it's way into the bilge. It therefore isn't coming from rain from outside.

I've removed the batteries that sit on top of my center mid bilge and vacuumed and dried out the mid and forward and aft bilges. As a result I've been able to determine that the water egress appears to be coming thru a limber hole that is at the forward end of the mid bilge. I've determined that there is an 8" area running to the starboard and port of the boat before there is a 2nd limber hole to the forward Bilge area. Access to this 8" area doesn't appear to be easily available. I've inserted a flexible mini camera with mini LED lighting and although I cane see blurry images there is nothing clearly observable in terms of water coming from within this area.

After a longwinded explanation of what I've done my question is, moving forward, how do I get access into this area?

Do I have to figure out a good location to cut and access hole/panel to allow me to further explore? Are there ways to access the area surrounded by fibreglass stringers that anyone is familiar on woth a Carver 350 Aft Cabin?

I'm considering putting the boat on the hard to deal with some other maintenance issues but I've been advised unless there is damage to the hull outside that won't necessarily help in determining any leaks. Partly due to the fact that in the water there is significant pressure on the hull due to the weight of the boat in the water and that won't be the case if she's out of the water.

Any suggestions from those of you with more experience would be greatly appreciated. I've attached two photos of the limber hole that is the source of where the water is from.

Is the water leaking in fresh or brackish? Do you have heat or AC running that needs to discharge condensate? Condensate can be discharged directly into the bilge or into a shower sump that could be non functional and therefor still drains into the bilge.

Thanks for the reply. It's brackish but only slightly dependant on the current tide. I don't have AC and during the winter only use my electric space and oil heaters and a dehumidifier that collects inside of it and I dump manually. I keep the humidity at 55% .I have two shower sumps both are working and dump via above waterline.

Are your thru-hull exhaust ports the kind that sit partially in the water? If so, check that area on the inside of the hull. I've seen these leak several times where they come through the hull.

Thanks I'll look into that. My problem is that the area where it's pooling appears to be inside a fibreglass area that I've yet to determine how to access without cutting an inspection hatch

A couple more to add.....what kind of toilets do you have ?..... where do they get their flush water and is that bilge pump discharge very close to the water line.

I guess that would matter if the boat only takes on water while after being underway though.

I doubt you have to cut an access hatch. If there's some kind of thru-hull fitting (that's the cause of the leak) there should be some kind of access to get to it. Might not be convenient or easy, but you should at least be able to see it.

We have a vacuflush fresh water that gets its water from our fresh water tank. The water tank and our water lines were empty and blown out so there wouldn't be any water in the lines. Even if there was residual water in the tank or lines it would have been minimal and drained by now. Also the water pump has been turned off since blown out so there's no pressure in those lines. The supply water line comes from forward of that bilge in the forward bilge and that bilge is dry. The limber hole that the water is coming from is aft of the forward bilge but forward of the mid bilge. Also, that bilge discharges about 5 inches above the water line and I can see the hose and the thruhull from the bilge in the engine room and there is no sign of water coming from the hose.

Viper,
They all sit out of the water. A minimum of about 4" to 6"

Thanks. Will keep that in mind
