Matt,

In line with this discussion, maybe you can affirm/clarify a squirmy factoid
from my past (ca 1975). We were simulating the electrical distribution
system for a DDE class of ships and I was told that: when you overload a
gasoline engine, it lugs down, complains, and lets you do something about
it. In contrast, when you overload a diesel (such as the ones that drove
two of the generators) it just quits. (The simulation was to train
operators and condition them to shed the load before the engine quit; among
other things.)

Thanks,
Roger

Skip,
As an engine professional for many decades I can tell you that all you
need is the two published numbers I hope are in the engines
specifications.
That would be the torque peak and speed and the horsepower peak and speed.
For a naturally aspirated diesel this is very close to what a dyno test
would give you.
Turn the HP back into torque (rev*tor/5252=hp)_ and plot it out as two
straight lines (it isn't, but it won't matter much). If I can find it and
you are interested, I could try to post the one page explaination of this.

Hi, y'all...


Back on the boat and about to pull the shaft and tranny to true the
shaft and plates and, perhaps, redo the MaxProp settings.

However, before I can do the calculations, though I have the pdf of
both the parts and manuals, I can't find anything about the power
curve.

Does anyone have them/know what they are, and willing to share?

Thanks.

Skip, on the boat for the duration, very small breaks excluded
