Hi everyone,

Found this video of an engine teardown, Delvac 1 ESP 5W-40 was used.

How does the environment for a marine engine compared to, say, over the road semi-trucks? The engine looks to be in good shape.

Thoughts?

Go to commercial marine operations that run gas and high speed diesels and HDEOs are what the operators run.

Very few freezing starts. Most bilges are above 32*F 99% of the time.

Loaded engines with pretty decent cooling (water/water heat exchangers, and oil coolers) running constant RPM for minutes/hours/days at a time. Very seldom overspeeds ...

Race boats are different. If they get "air" they can easily overspeed. That's why off-shore race boats have a throttle man who does that exclusively - keep the RPM in check when they air-out ...

Lots of diesel/electric kit - SCR DC phased out by VFD/AC - big ones run slow speed and 15 TBN marine Dino ... like MobilGard or Castrol MHP ...
