Ran sweet until 1 hour mark, noticed oil pressure dropping on just installed port engine, shut down, mechanic goes quiet, I start muttering. Check oil, down a couple litres, and obvious oil in the bilge. Finally found cracked remote oil filter hose underneath engine, limped back in on one engine again. Happy to report todays test run was perfect. <br /><br />After watching most of the reassembly, I'm even more confused about what could have gone wrong the first time. Seems like the rod bearings if plastiguaged have to be fine.<br /><br />Other thng we did with this rebuild was to go from a half to a full closed cooling, using existing 19X4 inch San Juan heat exchanger. Bit of creative plumbing because we were already teeing off hot water for a couple of heaters in the cabin and flybridge. <br />Manifolds and risers had a few mths on them and were flushed after each use. Despite what appears to be a smaller than recommended heat exchanger the boat ran at approx. thermostat temp. Going to increase the thermostat to a 180. <br />Couple of minor thigs to do and I think I'm ready for the season.
