Wellcraft Boat Owners Forum

I have a 2000 Wellcraft Martinique 2400 with a Volvo Penta 5.0L duo prop I/O. My question is, does anyone know for certain if there is wood in the transom? There seems to be very vague information about when Wellcraft stopped using wood in the transom construction. I am getting a bit of water in the aft bilge and one local boat mechanic suspects rotten wood in the transom. The various rubber boots associated with the outdrive were replaced about a year ago and seem to be in great condition. Sitting at anchor, I can hear water running into the bilge. After about 5 minutes or so, there is enough water to cause the automatic bilge pump to run. I'm hoping that rotten wood is not the problem as that would be about a $3500 repair to replace the transom. Any suggestions about what else to look for?

I'm sure you checked any seacocks and lines associated with them. I have one for each motor and one for the A/C. I would just sit down in the hull and attempt to find out the source. If your pumps are on in 5 mins, it should obvious. Go down into the berth and pull up the floor access doors and check them out. Check your Hull/Scupper flappers.

Thanks, discovered the problem was a leaking “Y” apparatus that routes the exhaust so it goes out through the out drive. Did as you suggested and saw where the water was coming in. Have now pulled the motor and the part is ordered. Discovered that the transom does not have wood in it and is composite layers of fiberglass. Part is about $450, so not as big a deal as I thought it might be! Yea!
