Fuel burn on a 250 DA

[boatman37]

Any idea what the fuel burn is on a 1986 250DA with a merc 260? I'm thinking about 10 GPH? Looking at buying a bigger boat and trying to compare fuel costs between different boats just to see the damage...lol. I typically cruise at about 3200 RPM at about 26 MPH

My 3200 pound jet boat with a 350 in it at 3000 RPM and 30MPH burns 8GPH

I would guess more like 13 to 15 gph at cruise

So sounds like you guys are around 10-12. Mine might even be a little higher because of the older technology? I filled it up last weekend so next time I top it off I will see what it looks like.

My 85 300WE with 5.7's and shaft's & props, 60-80 gal. 3 sob's running 300-3200 rpm's 12 gph each . Roughly 5 tons of boat.
Was told a rule of thumb HP x 10% = gph @ full throttle
