Now That's impressive! I wonder if I could mount such an engine in a
Bayliner? It should plane out quickly enough.

Wow!

I wonder what it redlines at? One cool thing about
the big commercial ship diesels is that no
reduction gear is needed, which saves cost,
weight, & maintenance.

G Probably around 105 RPM ..... more important to some would be it's
"barred speed range" (if any) and where it's at.

Stringer reinforcement highly recommended, and at more than 25 gallons
per minute the ride will be short. :-)

That makes my 454s look almost economical.

I'm not familiar with *big* diesels, but I was surprised at how slowly
that sucker turned, maximum power at 102 RPM.

Big squirrels run slow...

How the heck do they crank it to get it started??

We had a discussion about that earlier this year, answered by Rick our
resident LARGE diesel expert. To make a long story short, they use
compressed air stored in large accumulator tanks, and admitted into
the cylinder heads through a special set of valves used only for
starting the engine.

In an emergency you can hand crank...

....but not very much.

Air .....lotsa air... most big diesels on ships, have limited amounts of
starts when maneuvering. However, this has greatly improved with newer
ship. They generally have over a dozen, before they run out and have to
wait to rebuild supplies.
