Re: Fuel burn on a 53 W/871TI?
Not sure on a 53 but on my 63 with twin 12v71tis running with one generator purring I get around 0.8 mpg at hull displacement speed which is 1100 rpm at 8 to 10kts per hour depending on currents and wind

Re: Fuel burn on a 53 W/871TI?
A gallon per mile at 9 knots seems to be the feeling of most on the forum. I have natural injectors in my TI’s and we do a little better than that but it is close enough for planning purposes. Does not include the gen set, don’t understand why you would run a genset while underway unless you require Air con. Anything else except cooking can be handled by a good inverter. My 1 cent. John

Re: Fuel burn on a 53 W/871TI?
Those NMPG look like they're for a new boat with little fuel, water, furniture, tools, etc. A 53MY with 8v71TIs burns about 1.0 Gal/NM at hull speed 9.1 knots, with a clean bottom and normal fuel, water, etc. However, it burns about 2.1 gal/NM at 2100 RPM and 17 to 18 knots on plane. Running in waves reduces fuel burn some.

9 to 10 GPH at 9 to 9.2 kts above that and fuel burn skyrocket as you can see in the charts linked above
I m not sure I understand how running in waves reduces fuel burn or did you mean reduce fuel economy? Every boat I ve run with flow meters show a 10 to 15% fuel increase once you get out in waves or swells
As to a trip to the left coast via the canal it’s doable with careful fuel planning and plenty of time. I ve never done it but believe there can be delays thru the canal for pleasure vessels. Usually better tomship the boatLast edited by Pascal; 07-17-2018 at 02:16 PM.

Re: Fuel burn on a 53 W/871TI?
Yes, it was a boat test on a new boat, but the parameters are clearly stated with "7/8 fuel and 7/8 water and two people onboard with minimal equipment". Furniture would have obviously been what came with the boat, and I'm sure no tools were onboard.
Maybe that's inspiration for other owners not to load their boat up with so much crap.Randy Register - Kingston, TN
