Large marine diesels have very low RPM. Some of them red-line at 102 RPM, and normally operate much less than that. A typical passenger cars idles at 1200RPM and redlines around 6-7K RPM.
Then again a single piston in the marine engine weighs 2x of an entire car so they can easily do things that one wouldn't bother to do on a smaller engine.
