60 to 90 gals. I figure about a mile and a quarter to the gallon if I keep it at 3800 to 4000 rpm and just cruising. 502 mag MPIs in a 35 Fountain.

Yesterday, 5-6 Gallons in the Seadoo! Had great time on a sand bar in the Banana River.

Almost 100 gallons for the weekend :drink:

at 30 mph I get .8mpg total (twin big blocks pushing a 15000 pound cruiser. If we go cruise to an anchorage and chill out - then it is 1 gph for the genny/AC/Blender. Hard to average out.

I had a trip to West End in Bahamas from Fort Lauderdale area - 70 miles, then another 100 miles to abacos - was a 300 gallon day....OUCH. But then again - it's boating and nuthings better than boating.
