Good morning all. I have a 92 GLS175 SEA NYMPH. I’ve had it two years and it has leaked since I got it. On average about 3-4 gallons an hour. I have auto bilge and a switched bilge to keep me fishing. I have removed the fuel tank to see in the bottom. I have lifted it off the trailer and put Gluvit on the underneath. I have flooded it three times and one small drip is coming out of the port side runner on the bottom of boat. I also have the live wells plugged.(the inflow and drains). The boat has original motor (70hp evinrude). The transom was replaced about 8 years ago. What am i missing?? Any suggestions would be so helpful
