Our first bad news

The oil samples came back from the lab on Friday.

The motor and transmissions came back with clean bill of health.  The generator... not so much.

Potassium, sodium, and wear metals of the cylinder, pistons and bearings all very high.

Lab suggests that either this genny is in need of a major overhaul or just a bad sample.  Recommends that the oil and filter be changed, the genny be run for 25hrs and then resampled.

So, what does this all mean?  Well, now we have to come back with a conditional offer.  The genny has had its raw water pump, jacket cooling pump and heat exchanger replaced.  There may have been a problem that has been fixed and there are lingering contaminants.  The new parts may have been defective or improperly installed.

Irregardless, our offer is based on a healthy genny with the normal wear of a 1600hr engine, not an engine on it's dying legs.  On the bright side, the genny ran well through out the sea trial.  So, it is in good shape for now.

So, now we wait for the maintenance and oil samples
