5788 fuel burn.-gctid820128

We'll just got back from 2 weeks in the Gulf and Suan Juan islands. I tracked engine hour and fuel burn and was really pleasantly surprised. One big concern when buying her was everyone telling me the big Mans drink Diesel. Well it turns out they aren't half bad.

I calculated a total burn on both engines of 14 GPH. To me that's awesome considering a good mix of low and higher rev cruising.

More details and trip pics etc on my site at www.seattleboater.com

I'm psyched about the fuel usage. Break it down over 15 days and the $1010 I spent on fuel seems like a bargain.

Love this boat.

Love to hear real world fuel burn from other 57's ?

I come in a bit smaller at 5288. 1100 miles was about 12 gph at 14 to 15 knots. I'm on a new test run cruising at 12 mph and hope to get 13.5 to maybe 14 gph.

Best,

I just put on three thousand miles going Alaska this summer and with one exception always saw about 12 gallons per hour. I have often seen 8 gallons per hour down around 8 or 9 kts. The 12 gallon number usually represents many hours at 10 to 11 kts and some moderately high cruise at 17 to 18 kts.

just got done bringing the boat down to Portland from Anacortes. I departed Neah Bay and cruised pretty consistently at 1800 rpm (17kts) and arrived at Astoria 10 hours later. I refueled and used just about 400 gallons. That makes a fuel burn of 40 gallons an hour...ouch. Would not normally cruise at that sustained speed but wanted to limit my time on the open ocean and be at the Columbia Bar at an appropriate time.

Wow that's some long sustained higher speed nice job. Great to have a data point on the 1800 rpm spot. I had heard WOT on these was about 70gph.

I get 40 is steep but it makes me feel a little better about an hour or two blast at that speed when I need to.
