Water in forward and mid bilge

[km1125]

A couple pics would help here.

I'm getting confused hearing that these might be plastic or semi-flexible rubber. The only ones I have seen are either stainless or chrome-plated metal. Are we talking about the flange where the exhaust exits the hull??

My exhaust thru hull flanges are definitely somewhat flexible and not SS.

Yes,
They are plastic. I tried inspecting for cracks but could not verify. I have a scheduled pull once weather breaks. A tech from the marina is checking what I have observed.

You know I tend to be long winded. But for the benefit of others here are the steps I took (right or wrong) to find the source of the water in bilge. In the beginning I would have put money on one of the thru hulls in the mid or forward bilge.

Observed dry areas outside the stringers. Eliminated engine and Gen pick ups.

Checked water system for pressure holding by observing pump action. No cycling of pump.

Emptied water tank and heat water tank. Continued to get water in bilge.

Measured cycle of bilge pump at 30 minute cycle. Knew I was dealing with alot of water.

Run forward bilge until it ended pumping water. Bailed out bilge to observe ac pickup. No water coming from pick-up. Saw water running into bilge from the mid bilge.

Performed the same process for mid bilge. No water coming from the three thruhulls for transducers and speed temp sensors. Observed water coming into bilge from aft area.

Double checked shaft log area. Dry!

Showder sump dry.

Rudder logs dry

Found water last place I looked.

It makes me wonder why it failed? Lack of sealant when built? Flange hit something in travels? Why did this fail?? These were used widely on many Carver models. Hmmm?

Not to be smart ass Mike, but it is 19 years old..... 19 years is a lot to ask of a sealant that spends a lot of time underwater..
Hopefully it just needs resealed.

I would like to think that this would work, but am going to go the other way. I know for me, I won't rest unti the job is done properly. I would talk nicely to the travel lift operator and see if he can lift you out. Don't even block the boat, just keep it in the sling. Fix the repair and slide her back in.

But thats just me...if I didn't do that, it would be in the back of my head literally all season....

Walking around the marina tonight I looked at a lot of exhaust exits. Seems like early 90's when there was a transition from metal ones to some type of plastic or FRP. Seems more popular on the side exits than stern exits, although I did see one stern exit with some type of FRP.

Were you ever able to tell exactly where it was leaking?

Source of the post....I would talk nicely to the travel lift operator ....Don't even block the boat, just keep it in the sling. Fix the repair and slide her back in....

As a certified Travel Lift operator, I can tell you that this is an unsafe practice, and that no operator should allow it for the sake of the marina, the boat owner, and himself. For your own safety, never get anywhere near a boat until it is sitting on blocks and properly supported otherwise you're putting way too much faith in a pair of slings that you don't know whether the marina has been diligently getting stress tested ($$$). The way to a quick haul out and launch is to set the boat on a pair of temporary block piles, set a couple of jack stands at the aft corners and leave the slings on to take most of the weight, but the vessel must be sitting on blocks to comply with safety codes.

I agree though, it would drive me nuts all summer if I didn't get it fixed.

People up here don't comply obviously - I have watched them change my prop while sitting in a sling....
