In addition to having an expert take a look at this engine, I assume you would
also want a sea trial. The way the engine starts up, or doesn't, and the way
it runs, or doesn't, will tell you most of what you need to know. You could
probably expect some rough starting, followed by either some blue or white
smoke. By time the engine warms up to full operating temperature, the
roughness and smoke should clear up. Find out what the max rpm for the engine
is (ought be in the 3400 to 3600 rpm range) and see if you can pull those rpms.
Listen, and look, hard when you do this.
If it starts and runs smoothly, there is a good chance you will have a boat
with a great engine. If it doesn't, you may want to pass.
Thanks for the input and wise advice. My main concern is that when an engine is
idle for a long period (whatever that means) the oil drains from the cylinder walls,
and condesation deposits water on the walls, leading to rust. In this case, (let me
hasten to say I'm not a Diesel expert), I'd expect the compression to be low(er),
resulting in a hard start. Plus, if severe enough, excessive blow-by would show
up as blue smoke.
Actually it's a moot point now. I visited the boat (Sun 27) this morning,and noticed
bright spots in the hull while diving into the bowels of the V-berth lockers. It was sunlight
shining through "thin" spots in the hull. Voids? That, plus the hull to deck joint seemed
to be secure with 10-32 bolts on 1 foot centers, was enough to make me walk away from the boat,
The search goes on.
