fuel consumption

Can anyone give me a rough idea of the fuel consumption at cruising
speed,in flat water, of the Yanmar 28 hp ?

Aloha,

Hi James, I bet a few folks have experience. My diesel is a Yanmar 3GN30 27 HP it cruises at about 5 knots at 2400 RPMs and uses about a half gallon of fuel per hour. Happy motoring. Oh and if you can put up some sail it helps.

Hi Jim and the group,
Regarding the fuel consumption of the Yanmar 3GM30F. I think Kate is real
close. Last year four BCC’s sailed down to Baja and up the Sea of Cortez.
A lot of motoring. I compared notes on consumption with Mike Pearson and we
both came up with the following.

I have the exact figures aboard but my boat is in Mexico right now. What I
remember is the consumption doubles between doing 4 knots to 6 knots. When
I am motoring in a dead calm at 6 knots, 2800 RPMs, I burn half a gallon per
hour. When I slow it down to 4 knots I burn about a quart per hour. I
found that the condition of the diesel is a factor. Surprisingly, I found
the diesel in Mexico to be almost crystal clear and it burns clean. I never
had to clean any exhaust off the transom. I also feel a good diesel
additive will help keep it burning clean and improve consumption. Needless
to say, the condition of the bottom has a major effect as will a light wind
or current. I agree with Kate, a little sail up and filled, really helps.

Fair winds

James-

My average fuel consumtion over the past four years during various
conditions is

0.57 gal/hr @ 2400-2700 rpm making 5.5-6.5 kts good.

original screw was a 16RH11 2B Sailor 1".

replaced in '98 by a 16RH12 Michigan MP.

I have no data on the Sailor.

Clean bottoms make a HUGE difference. I rarely have one.
