Wow! So many responses; thank you all!
Apologies for not checking back sooner. This week has been, well, .. I'm sure you all know.
Lots of new systems, lots of things to fix. I had focused primarily on domestic systems and only took her out to stretch her legs yesterday.
Thanks DougR.. I suspect you're right about the transmission pressure. I'll check it first.
The transmission seemed to run fine for the little 5NM jaunt, and temperature eventually settled in at 190, verified by IR heat gun.
However, rather alarmingly, this morning when I went to head
over for a pumpout, the engine started making a terrible shringing noise
while throttling up. It would stop once it reached its target RPM, so it sounds like some bearing is not getting oil. Rather alarming. I went back to the slip immediately.
I'll post another thread as I haven't been able to find anything useful, mainly because I'm not sure how to describe the sound other than "shringing" .. and apparently I'm the only one who uses that term.
Anyway, I'm in a hurry to get on the road and head
back to Montreal where I have to take care of shutting down my shoreside life, so I'll read the rest of these responses when I get home.
Thanks again everyone!
