Our last correspondence with the list was May 2009 shortly before we
sailed from San Francisco to New Zealand. You can find passage

Yesterday I learned that we may have a NZ$23,0000 problem or a $7,000
problem with our 3,500 hour ten-year old  Fischer Panda 10 genset (now
called a Panda PMS 12000). The heat exchanger outlet sea water hose
clip failed catastrophically  -- resulting in 35 litres/minute
flooding the capsule. The sea water level rose enough in the capsule
to enter the asynch alternator housing, destroying the winding
insulation.

The genset is now on the workbench at Enertec in Auckland. Colin
called yesterday to say he thinks the Kubota D722 should be replaced +
entire new Panda alternator end = about $21,000 so better to buy new.
Colin's worry about the Kubota is he found a lot of oil sitting in the
air intake muffler box. That could mean a top end rebuild, but given
the challenge of servicing a genset, we would do rings and bearings,
etc. too.

My question: is it more likely that the oil found in intake muffler
came from my overfilling the sump two weeks ago? I'm not sure I did
overfill, but it is possible that while replacing the GCF oil bypass
filter that I added too much Delvac MX. Dipping looked high but after
running for a few minutes to refill the GCF filter and cannister the
level was right on full.

I'll post a separate query regarding the wisdom of rewinding the
asynch alternator vs. replacing the whole thing.

Thanks in advance for any tips!
