Hi Charlie
I am a 501 owner.* Some say that you need to run the 6v92ta's hard.* I dont.* I have been running my boat for years at 1100-1200 (8-9 knts)*Gets just over 1 MPG*at 1200 RPM (not good for a trawler but not to bad for a 60k lbs motoryacht. The only thing you must remember is not to let them run at idle speeds too long.*And change the oil more frequently if you dont run harder.* *Look at all the sportfish that run 600rpm for 8-10 hours a day.* The nice thing about the 501 over a trawler is if you need to kick it in the a** you can.* She cruises nicely at 2100 Rpm at 18knts.* But the Diesel will flow at that speed.
