Assuming your temperature gauge is accurate, 220-230 is way too hot.
A raw water-cooled diesel should run 130 degrees or so. Freshwater
cooled, 30 degrees or so higher. 220 is the point where you start cracking
the engine block and warping things in the engine.
I assume you can't tell whether water is coming out of your exhaust if
it's underwater. That would be the first thing I would check. An bad
impeller, a clogged exhaust elbow.
Whatever, don't run your diesel that hot, or you will soon be buying a
new one.

Subject: [IC27A] New Question--Engine Oil Alarm
It looked like the board needed new questions but more importantly, I need
answers, so here goes....
:-)
There wasn't much wind today so we came back to the marina under power for
the last 30 minutes or so. The engine (5411) was reading a little hot (220 -
230) but not a big deal. As we came closer to the marina, I powered down a
lot, went into neutral and then heard the engine oil alarm. I heard it every
half second (not a consistent sound like when I prime it) and then I put it
in gear. The sound was still present and still inconsistent. I made it into
my slip without a problem. I checked the oil, but it wasn't low.
After cleaning up, I started the engine to try to replicate what I heard
but could not. I had it tied securely and put it into gear and kept it there
for several minutes at around 2200 RPMs, then revved it in neutral for a
while, put it back under load but could not make it happen again. Any ideas?
Also, unrelated (or related...I don't know); when moving forward under
power, is everyone's exhaust under water and if so, is it white because of
the outside temperature (low to mid 50's), is something wrong or is that
normal?
Thanks in advance,
Michael
