Chuck,Now that you mention it the thing that bothers me the most is the noise
of the engine running that fast while in the slip. I do not know where he got
that idea except that he worked for the railroad. Of course the diesel engines
in the locomotives are a little larger than the one in his boat. I doubt that
they were run at a high RPM when sitting still in the yard.

{}#yiv5359827397 Frank,If your friend is tied up in a slip and putting his
engine in gear at ½ throttle for 5 or more minutes, he better put some chafe
protection on oversized dock lines along with some really robust bumpers,
otherwise he may be calling am insurance agent rather than a diesel mechanic.
I also wouldn’t want the adjacent slip that has to listen to that engine
churning away each time he comes down to the boat. At diesel class at
Annapolis School of Seamanship, the instructor said it was more important to
run the diesel for a longer period of time (like ½ hour or more), even at lower
RPMs to let the engine get up to full operating temps than to run it for 5-10
minutes to get the boat out of the slip and the harbor and then shutting off
the engine immediately when the sails go up. My boat is on a mooring, so when
I go out to the boat, I’ll start up the engine while I’m prepping the boat for
sailing, which also gives the batteries a bit of a booster charge before
heading out. I have to wait for a draw bridge before I get to open water, so
30 minutes of powerboating isn’t a big inconvenience, more like a necessity for
me.Chuck GilchrestS/V Half Magic1983 Landfall 35Padanaram, MA From: CnC-List

Subject: Re: Stus-List Warm up diesel engine I forgot to mention if it should
be in gear. 850 to 900 is about the same as the normal idle speed on a car so
that sounds about right. On Monday, June 20, 2016 10:42 AM, Joel Aronson via

A friend of mine insists that you cannot warm up a Yanmar engine at idle speed.
When we are still in the slip he puts it in gear and runs at about half
throttle. None of the other sailors appear to do this. Unfortunately many do
not give the engine a chance to warm up at all. I am open to suggestions and
the reason for what you are doing. Frankc/c 29
