I was curious to see if anyone else has been in my shoes on this issue. My '89 3807 Aft had the little holes at the aft port and starboard for the exhaust and AC's. I was getting some serious carbon monoxide through some kind of make shift fiberglass repair to the fiberglass "exhaust chamber." on the starboard side. And the stainless heat shield had come off and was causing some serious rattling and vibration. So I contact the good people at Carver and they sent me an exhaust conversion instructions to put mufflers and go straight out mid ship to bypass the bad design and issue.

So I did the conversion... Love it. So much quieter. BUT.... now I have exhaust leaking through my aft port and starboard windows....

Guess the felts and the windows need to be resealed / rebuilt?! I have no clue how to do it or where to even start.... Pretty frustrating to spend all that money and still have the issue.

Anybody got any guidence? I appreciate it!
