Re: Trawler Fuel Consumption

All I can say is Impressive! Although with a boat that size would prefer twins.

What I have in mind would be similar to the comment posted by "Boatpoker" in November of 2008, as follows:
"My 38 year old trawler with a 38 year old Perkins HT6-354 (diesel and turbo-charged) went to 20,000 hours before we rebuilt it 2 years ago. It makes the run from Toronto to Dry Tortugas or Bahamas and back on less than 800 gallons at 1.6 US gallons per hour at 1600RPM and 7.5 knots."
I'm sure that this group could provide a lot of information on this topic.

Thanks for any contribution that you can make.

Hey Seasalt, thats pretty good mileage. 38 years yours must be one of the first turbo perkins. Most people say with a turbo the life is cut short but your engine proves them wrong. Thanks for the info

The information posted by Boatpoker was very helpful because it indicates a much lower fuel consumption than I had been told for the Perkins 6-354. One broker told me to expect to burn 5-7 gallons per hour with twin 6-354s. He didn't say at what speed, so it is helpful to know that Boatpoker could make 7.5 knots at 1600 RPM with one 6-354 in a 38' trawler. It's hard to find specific information like that. I'm hoping that others will have similar reports.
the energy density of disel fuel is approximately 30% greater than with gas so it can do more work but the high cost of disel engines sorta offsets that. My preference is for disel because of thier low end torq and fuel efficiency even though i understand they are more expensive than gas engines
