20ft. CC scupper repair/replacement

I did a search, and now I can't find the thread from 2007 re: scupper repair. Could someone enlighten me?

Question: Does the front "fish locker" scupper have a block of wood around it? How large is the wood block? Is it glassed-in? How much of the block can I dig out before compromising the block itself?

I'm getting a LOT of water in the boat (pumping out about 2 gallons every 35 minutes!). Transom was replaced, so I know there is no leakage related to it. I'm planning on repairing/replacing all 3 scuppers, and am curious about the size of the block surrounding each one.

Thanks. I'll try to post photos about the transom replacement when I have time. There were 13 holes that had been drilled/plugged in the transom, and lots of soggy wood. It came out very easily, according to Craig Bosman of Coastal Fiberglas, who did the replacement. He said he prefers to work on completely trashed transoms, as the wood comes out so easily.

So, the transom repair did NOT solve the water leakage. The only place water could be coming in is the scuppers.

Here's a link to post I made on the scupper repair I did in 07. Scroll down towards the bottom of it to see the pics I posted of the repair. The photobucket link no longer works but the pictures are still there near the end of the post. The leak you describe sounds like it could very well be the scuppers.

I'm not real familiar with the fishbox up front on the CC's, but I don't think there is any wood around the drain up there. I believe that fishbox was just bonded to the hull with putty before the inner liner with the fishbox hatch was dropped into the hull. Denny

Thanks for the link. That's the thread I couldn't find a second time.
I'm finally going to have the boat in my driveway, as it's now sitting 80 miles away at Lake Anna (the epicenter of last week's earthquake!). I'll get a much better look at it before I embark on a repair. If the fishbox is simply bonded to the outer hull, I would think a repair would be rather straight-forward.

Anyone else care to weigh in before I naively move forward? I appreciate the cumulative knowledge here. Thanks.

Denny's steered you straight.

Well, the scuppers are all replaced. Won't get the boat on the water till next week, at the earliest, so...

I asked Coastal Fiberglass to do the repair. I worked with him (Craig Bosman), and he's a "get her done" sort of guy, and isn't real big on finesse. He thought the method described here was way too complicated, and right or wrong, I let him do the job anyway (We're just trying to get the boat on the water. If we decide to keep it, the ensuing repairs will be a bit more fastidious).

The front scupper was mounted in what appeared to be closed-cell foam. It didn't appear to have been compromised, although it felt a bit damp. Unconcerned, Craig cleaned it out, slathered a good bit of "Life-Calk" on the new (plain sleeve, one end flared) bronze scupper, and we used the flaring tool to flare the other end.

Did the other 2 scuppers the same way. The port scupper had a hole on the stern side of the wood block, and Craig thinks this is where the water was getting in. He used a router bit to grind away some material. It didn't seem to be rotted at all, just a void in the wood. He filled the hole with the Life-Calk before inserting the new sleeve.

This was not the way I would have done it, but in reality, this boat will never win any awards for fit-and-finish, and given the condition of the boat, I felt the 'quick and dirty" replacement would be just fine. I don't have the time or expertise to do the job myself, although now, after having watched it done, I know how to do it next time.

Hope the "next time" doesn't come too soon...
