Fuel Consumption for Sea Ray 310 Sundancer

[thbouro]

Hello everybody,

I am looking for the fuel consumption for a 2001 Sea Ray 310 Sundancer, powered by two Mercruiser 350 MAG MPI with V-Drive. Also, for the cruise speed and the engines rpm.

Thanks

Is about 0.83 Gallons to 1.2 Gallons per mile

We have the same boat, have you had any other problems?

I used to have a Celebrity 310 with twin 350's. I got about 1 gal / mile at cruising speed as well.

On a boat, there are too many variables that can affect fuel consumption. Two identical production boats with identical engines can have vastly different fuel usage. The best thing for you to do is to purchase and install a FloScan (or similar) fuel flow meter. This is one of my most useful navigation tools and has paid for itself over and over and over again.

Thanks everybody for the replies. I have already installed an aviation flowmeter and the initial output is about 1.2 gal at 3800 rpm (seems to offer the best consumption) at about 20 kt, does it make sense?

What units are you using for measurement?

The consumption is measured in litters per nautical mile and I converted them to gals per nautical mile, speed in knots, distance in nm.

Thanks

That being the case, 1.2 gallons per nautical mile is very realistiic for that boat. Have you collected any data at hull speed or perhaps 90 percent of hull speed?

Well, the hull is in a good condition but the propelers have some marine growth.
