Diesel Engine Choice?

In article , says... 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. Capt. Jeff Single screw? What sort of headway do you make at 2000 rpm? jps 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. Capt. Jeff |
