I have a 1985 26' Oday with a leak that is coming from the metal tubing that attaches to a 5/8" (??) reinforced hose. This is the metal tubing that connects to the bottom of the cockpit floor. The line to drop the keel comes up through this tube and into the cockpit. Is there a source for this tubing or do I just bend something up? I tried to stop the leak but the location is one of the toughest spots on the boat. Without having to haul the boat, any ideas??
