[C320-list] Overheating alarm Yanmar 3ym30-2006-Hull #1089

Apologies in advance for the lengthy question!
Wondering if anyone has had a similar problem: I have no previous
experience with diesel engines, (the 320 arrived at the dealer in May
2006) and had not tended to use the engine for more than docking and
getting in & out of the creek to the Bay. The overheating alarm went
off once or twice on very hot days last year, and, thinking of it like
a car engine, I figured it was weather-related and shutting down the
engine made it go away. This season, using the boat more and traveling
on some windless days, I discovered that running the engine at 3000
rpms, after 20 minutes the gauge showed about 220 degrees, and the
alarm would go off. (There were no clogs or problems with the cooling
that we could find.)
Our marina called the Yanmar local technician who found that the
engine temperature was running about 40 degrees lower than the
pedestal gauge showed, and the tach fluctuated when running the blower
switch; and he replaced the sender switch. He tested it at the dock
for half an hour: no alarm. I took the boat out some days later and
the alarm went off after 20-30 minutes at 2500 rpms, gauge again at
220-230 degrees. An electrician from Yanmar came and found a "problem
at helm where Catalina splices harness for their dash panel, 2 ground
wires were screwed onto bus bar & screw was 90% on wire insulation...
" which he cut back and reconnected.
I took the boat out and ran it at 3000 again, and after 20 minutes the
gauge went up to 220 and the alarm went off again. Dropping down to
2500 the gauge stayed up, dropping down to 2000 the alarm finally
stopped and the gauge shows 180. And now, the autopilot seems to
engage when the 'auto' button is pressed, but if I select any of the
degree buttons to adjust course, the autopilot flashes "drive stopped"
and does not adjust course.
I'm told the boat is out of warranty at this point and, apart from the
$500 spent on the 50 hour Yanmar warranty service, I am so far in $800
for the electrial work, which seems to be faulty installation during
the boat's construction. What I'd like to know is--what is the normal
operating temperature for this engine at these speeds? At what
temperature / operating rpms would one normally expect the engine to
overheat and the alarm to go off? And has anyone with a 320 built in
the past 3 years had similar problems with the electrical installation
at the helm? Our engine has around 100 hours on it, we only had it in
the water for 3 months in 06, and last year, due to an incident with a
powerboat wake, we also only had it in the water for 3 months of use.
This has been our first 'full season' of sailing.
Thanks much,
Susan Rasco
