Jerry Clark H356 SV Persistence

I am helping a friend take a Cabo Rico 38 from Kentucky Lake to Charlotte Harbor down the Tenn Tom in early November. He has not motored or sailed the boat very much since he got it and does not know the hourly fuel consumption at 2,700 to 2,800 RPM at cruise. He has 105 gallons of fuel. Does anyone know the apoximate hourly consumption? Thanks

Allow 1 quart per 4 hp per hour

That is pretty much standard for diesel engines. That is not rated hp but actual shaft hp delivered.

I use 1/2 gal per hour

For my Westerbeke W30 in my 32 Oday cruising at 6 knots and that gives me a rough idea of about how much fuel to add to the tank and I been checking this with the not so acurate fuel guage but its close enough. I would guess that the W50 is close to this GPH

Thanks for the responses!

We're leaving Kentucky Lake on the 28th of October, down the Tenn-Tom to Mobile then to Charlotte Harbor. By the time we get down the Tenn Tom, we'll know the range well, but we wanted some idea before leaving. Thanks to both of you.

Far to high!!

At the rate of 1 quart per 4 hp I should be using 2.5 gals per hour. I use more like 1 gal per hour with a Westerbeke 50.

I have a Westerbeke 44B Four

I have a Westerbeke 44B Four and burn roughly .6 gal per hour at cruise which for me is 2200 rpm's. At 2700-2800 I'd think you could be burning as much as .8 - 1 gal per hour.

Steve, The fuel comsumption rate on any diesel

engine is determined by the power consumed not the rated HP. You may have a 50 HP rated engine but at cruising speed you aren't using 50 hp. Probably closer to 15 hp.
