I am aware of air in the lines issue, it once made me very
frustrated. Most diesels, hopefully this one too, quickly clear that
once they start running. They suck in a lot more fuel than they use,
and return the unused fuel back.

Oh, and this DD diesel is meant to be started with ether.

The 12V71s had a reputation for the rack jamming (actually, the governor
link) and running away.  Our machinist mate told me (but I never saw it
happen) that he had something like 15 seconds to lift the hatch, jump
down in between the engines, pop the rack cover, and manually jack the
rack to OFF.

I think I'm glad I never did see it, as that engine had a max working RPM
of 2450 on the boats, and supposedly red-lined at about 3600.

My DD353, there is a intake shutoff, just pull on it lightly and all
intake is stopped.

I lifted the engine yesterday (on blocks). The pan has a small leak, I
put a plastic tub under it.

I ordered a gasket, when I reinstall the oil pan, I will be sure to
have a shutoff hooked up for easy shut down.

We had just one Fairbanks-Morse (nuc boat).  But it had an intake
flapper you could trip from the deck above the diesel engine if you had
a runaway or such.
