I have a 38 moorings 1991. Have it at the yard for the last 5 weeks. Water keeps filling up in the bilge. Had the keel resealed, bolts tightened and water is still coming in. Put food coloring in the 3 tanks and water still coming in but not from tanks. Have a scematic of the water lines of the 38 and they will try to pressurize the lines to see if one is leaking. Checked everywhere else and no leaks. any thoughts with this model. went sailing over the weekend light breeze and got back and the water filling in the bilge started again.
