I've been eyeing these as the "next" boat. Must have diesels though... Most seem to have the Cats. What are you guys getting for mpg? I was hoping it might get close to 1 mile per gallon with diesels...

For all you guys with the 8.3 Cummins what RMP do you normally cruise at.I have been running between 2200 to 2250.At 2250 I am averaging 24. 5 Kts .What do you guys thing is the most efficient RPM to run these motors.Thanks
What do you guys have as your WOT with Cummins 450Cs?
I had Cummins survey my motors the tech reported 2680 and 2670 at WOT he recommended that I should have the wheels worked to get an additional 100 RPMs.I believe Tony Athens on boat diesel .com suggests 2800 top end for the Cummins 450 .What do you guys feel is the best RPM to run these motors for optimum longevity and fuel effiency.
The built in vacuum on our '97 40' Sedan Bridge doesn't seem to have much suction power......I've changed bags (though I used a smaller/shorter bag - the neck fit the cannister) with no noticeable change.
Any tips if I've missed something will be greatly appreciated by the Admiral.
Thanks

Ours works exceptionally well. You may have a leak in one of the hoses or hose outlets.....
