Information please
When I was overseas, I was sent to a small ship to ck out the engines.
Only took a few hours, and I don't remember the designation of the ship.
I had a pair of 4, 6/71 engines for the mains. Also had twin 50s aft and one
Forward.
Any information appreciated.

Redhawk thanks. That is an M boat. They had twin 6/71s.
Did some time on those also. LCUs had three 6/71s for mains.

I think PBRs had two Detroits and were jet drive.

They beat me to it. Anything that small wasn't a ship, it was a boat! BTW 6 is the number of cylinders and 71 is the cubic inch displacement of each cylinder. A 6-71 is 426 C.I. and an 8-71 is 568. These old Jimmies were two cycle and very noisy!

Yes, we called the V configuration Jimmys "double breasted road oilers". I wonder what you marine guys called them?

They may have been ARVS, we were turning them over to the JSDF
The v12/71s are very noisy.
v6/268s not so bad.

Closest ship I can find are the cyclone class costal patrol boats. The cyclone class is larger, though.
Thanks for all the comments.

Around here loggers and sawmillers used them, 6-71's and 4-71's. You hear them moaning miles away. Called the oil-a-matics.

Had 6-71 as a pony motor that turned the fan on a vacuum truck I think that was the biggest contributor to my hearing lost

We had a 1950 Oliver tractor with the 6-71. My late father used to say the same. There were times when pulling the big plow or our silage chopper that the exhaust manifold would glow redish/white at night. Compared to our 1850 Oliver, the 1950 was a beast. I've always said I'd build an old pickup and put a 6-71 in it, just for the sound and the nostalgia. But, I never have... I have used a few 6-71 blowers in my life however.
