A new boat for us - year 2000 Regal 180 LSR with Volvo 4.3 GL with SX-M stern drive.
Second trip out was about 45 minutes in calm water. Upon return noted water in the bilge and turned on the pump. Hard to guess volume but perhaps 2-3 litres of water expelled. Cranked up front of trailer and removed drain plug. Perhaps another 1/2 litre of water. Screw plug back in but water continued to dribble. Looked like it was from around the edge of the brass flange where it meets the gel coat. The flange is screwed into the boat with four screws and appears to sealed. I think the seal/caulking in the site of the leak.
Two questions and excuse my ignorance as a new boat owner. (1) How much, if any, water should I expect to accumulate in the bilge while driving? Is it possible that water will accumulate while driving but not while moored? (2) How difficult is it to remove the drain plug/flange assembly in order to reseal? And to reseal what do you suggest? The local marine store has a number of #M products ? 5000 series I think??
