sorry, shen, but the author clearly stated the engine was gasoline.

I own lots of engines. I laugh at idiots who make idiotic statements about
engines.

btw, the ill-fated fishing boat in "The Perfect Storm" had what kind of
engine
installed.

I guarantee you, it was a gasoline engine, according to the author of the
book.

So, was it a gas engine or a diesel or a steam engine or a nuclear reactor?

G I'll guarantee you it was diesel.
No commercial fisherman with a boat that size and the requirements placed on
the engine for continuous operation and power take-offs would be using a gas
engine.
I'll let others argue torque, reliability, time between overhauls, HP and
fuel
economy.
