Does this seem right?
On our recent 5-day trip to the lake we put 25-hours on our BBC 22. Near as I can tell we burned 200-gallons of fuel. We spent a lot of time skiing and tubing in the 2500 RPM range but also did some cruising, maybe 50/50 or 60-ski/40-cruise. Anyway, 200-gallons @ 25-hours equates to 8 gallons/hr. I may have used a little more fuel but not much over 200 gallons.
This seems really low for fuel usage since a typical cruise will burn approx. 30 gallons/hr in our boat. Even though the RPM's are low for skiing I'd think the motor would still burn a good amount of fuel pulling a load at slow speeds. Maybe it's also the effect of a lot of idle time during skiing?? I'm just trying to get a better idea of how much fuel we burn since, as mentioned in other posts, the gage can be iffy. I though we were good one day only to find out we had 2-gallons left in the tank after filling up.
I guess I should be happy we didn't burn the 30 g/h over the 25-hours since the actual $750 gas bill was bad enough.
