Hi. I recently found water in my Yanmar 3GM30F engine compartment. The raw water outlet hose connector of the heat exchanger worked loose. I have no idea how. The set screw was tight. I thought it could be caused by pressure buildup but the raw water is discharging nicely, so there's no blockage. I took off the side cover, loosened the set screw, pushed the connector back in fully, tightened the set screw and reattached the side cover. I didn't have a replacement gasket for the heat exchanger side cover.
- Where can I source a replacement gasket (RESOLVED: Toad Marine)?
- Any ideas what would cause the outlet hose connector to work loose?
