Good news from Yacht works.

The Nanni (our get home engine) took on water through the exhaust. Apparently when it was installed the air lock was not high enough and sea water found its way in through the exhaust and ended up in the oil pan. this caused the oil level to increase to the point where some of the oil was entering the compression side of the cylinders and caused the engine to smoke terribly.  Also the engine would  continue to run (on the oil) for a short time after the ignition was turned off.  Yacht-works discovered the problem and will correct it. The good news is that the analyses of the oil came back and it showed no significant wear of the engine.
