I believe that the manual dampers were actually a Detroit Diesel
furnished device as they were common on engines that ran mostly
unattended like air compressors.

Yeah... I wasn't commenting on who made them, but just when, in the line of
models, they came.

They definitely were NOT on the Mk-I boats. I spent a good deal of time in
the bilges on that model.


The dampers are a relatrively recent invention, like 1970s


The dampers are common on civilian stuff.
Probably typical military BS in believing the contractor knows what they
are talking about when they said "Oh those things aren't needed"........
OR they were afraid that they could get tripped and kill the engine (and
the crew if it occurred at the wrong time)

There is one time they don't work. If the engine somehow gets started in
reverse direction of normal rotation! One of our crew did that at a
fire call. He had pulled the rig into a driveway, left it in reverse and
jumped out. He forget to pop the brakes!!! Thing was nice and warmed up
from the trip and it turned over about twice and fired up! Was dumping
exhaust out the intake boxes and gulping air up the exhaust. The driver
was freaking out. I walked over, told him to jump in, pop the brakes and
stand on the brake pedal. Then just shoved a traffic cone in the
exhaust. It died pretty quick between the gearbox and choking it.

I said normal rotation because the Detroits were built in clockwise and
counter-clockwise rotation depending on application. Plus some were both
and you shifted the racks to reverse the engine.
