Engsol! Engine would start-run for 3-4 sec and die,then I started again
after I checked thermostat-was OK,changed oil and filter.,I pushed the
throttle almost to the max ,black smoke,muddy,greasy,heavy smoke came out
with some water-engine run for 2 min and continue spiting this black water
and stopped abruptly,cut like a knife-mechanic was present when we did that
and said that he doesn't know what is wrong.He has spent 2 hours checking
what was wrong and left me without answer.Of course took the money for
trying.

Hi! I need your expertise or opinion.
I have diesel engine Volvo Penta MD3 on my sailboat .Just after refueling
in
one of the marina(in 10 minutes) engine reached temp 280 F
I had to run the engine for another 8-10 minutes to drop the anchor and I
shut off the engine which was red hot.I suspect that they pumped 20 gal
gasoline instead of diesel.Capacity of the tank is 40 gal.I still have
this
fuel in the tank.How can I check if gasoline is in the tank,mixed with
diesel ? Is it any method,way to analyze or find out.Maybe I should find
the
lab or place that can be determine what this fuel consists.
If they pumped the gasoline accidentally or not the engine is probably
damaged.Thank You For Your Help.

Steve's suggestion of putting a sample in a jar is good. I'd also suspect
that
the sample would separate after a few hours...gas on top, diesel on the
bottom.

You mention above that the engine was "red hot" after shut-down. What were
the indicators? The temp gauge only? "Frying" noises and smell of a hot
engine?
Smoke/smell from hot paint? Could a stuck-closed thermostat be the
problem?

One thing I'm curious about is how the engine ran with a 50/50 mixture.
I'd
think that since gas has a much lower flash point (it does, doesn't it?),
it
would have ignited earlier in the compression cycle, and made a heck of a
racket,
and that power would be low. Also, I'd think the exhaust would be quite
smoky.

Good luck...hope your mechanic says all's well.
