[C320-list] Oil changing pump kit

[Quentin Murphy]

Changing the oil is the easy part.  It takes about 15 minutes for the engine
block and 5 minutes for the gearbox using the dipstick hole in both
instances.  It can take a while to get the gearbox dipstick aligned so it
will screw back in however (no, the plastic threads are not cross-threaded).
I use the tall manual oil changer (4 Qts) which I believe is sold by WM,
which I place forward of the engine and lead the plastic hose arrangement
aft through the engine compartment.  What is a real pain is changing the oil
filter as some old oil always spills into the engine tray below.  I use lots
of paper towels for that unpleasant task and still some gets out to under
the engine, on your hands, etc.  Changing the filter is the messy part of an
otherwise simple task.  As I don't go over 100 engine hours annually, I only
change the oil and filter immediately prior to (Winter) haul-out.

Bruce, on my Perkins M30, there is a pipe from the bottom of the sump that
comes up alongside the engine by the oil filter.  It has a treaded connector
with a pipe nipple in it.. To change the oil, I replace the nipple with a
threaded hose barb, connect the pump hose to that and pump.  It takes about
5 minutes or so to suck out 4 quarts.  It's easy and clean.  When done, I
unscrew the hose barb, replace the nipple and go dump the oil at the marina.

Apparently, Yanmar engines don't have such a pipe into the sump.  Some have
replaced the drain plug with a connector and a hose permanently installed by
which the sump can be completely drained.  However, leaving a hose and
connection in-place is inviting disaster.  I don't know that I would do that
unless the connections were threaded and the hose was a copper pipe.

BTW, commercial fishing boats often have tanks of clean and used oil
connected by pumps to the engine.  They can shut-down and change oil in
minutes and be back up without getting their hands dirty.  All connections
permanent, throw some switches and your done.
