I have this engine in my trawler and am very pleased with it so far. It
has 2200 hours and runs like a top. I switched it to Amsoil 15-40W
marine diesel oil run through a bypass filter and hope it will give me
20,000 hours. I run it between 1600 and 2000rpm and get about 3mpg. Ask
me when I'm even older and I'll tell you how it worked out.

Single screw? What sort of headway do you make at 2000 rpm?

Single screw in a 36 Monk. It does about 9 knots at 2000 rpm, 8.5 at
1900 and a little over 8 at 1800, depending on how heavily I'm loaded.

I just did some research with Cummins and others to find out how slowly
the motor could be run for extended periods without problems. It's a
turbo and there are issues if the thing doesn't spool up fast enough and
heat up properly. i am told to go 1500 at a minimum, maybe 1600, but to
make sure it's running at the regular operating temperature.

I'm doing the Great Loop this year and the difference in operating costs
between getting 3 mpg and 3.5 mpg will buy a lot of beer.

Cool, thanks for the info. Having grown up with twins, I'm in awe of
those who dock their singles in tight spaces, especially the ones
without a thruster...
