If you have been in the military or have fished or logged you have worked around them.
If you remember in the the movie U-571 the skipper is describing his dad's fishing boat to the Chief .
"Rotten to the gunnels, Stinks like fish. Noisy old two stroke diesel "
No problem with this was 1942-44 His two stroke was more than likely a 71
Just a small time problem if the 71 came out in the mid 30s his old two stroke would have been cutting edge tech.
