The fuel lines seem to have seated themselves, no leakage this last trip. But it would seem the old engine has a new issue to be resolved, I'm thinking it's related. Engine starts smooth and settles into idle quickly but motoring back into the harbor I noticed some light grey/white smoke out of the exhaust. Then an engine alarm went off. I turned off the engine, sailed back to the mooring on the jib and engine started and ran normally when I started it on the mooring. What would the alarm indicate? Related to the smoke?
