I filled my tanks last Wednesday then ran the boat home from Detroit Beach Boat Club a run of 18 miles. Then on Sunday I took my boat out for the last time this season. I made a run around Grosse Ile then filled up at Elba Mar Boat Club. Using the trip odometer of my GPS I ran a total of 36.5 miles (statute) between fill ups. I put in 36.9 gallons of fuel on Sunday.

On this particular tank of fuel I averaged 0.989 MPG on this last run. I ran at RPM's of 3200 to as low as 1600 during that 36.5 mile run. It's really the only time I tracked an individual use of fuel. I did keep track of my total mileage this season and gallons of fuel used so I will have a seasonal average MPG to post later and I tracked my hours run so I will also later post my GPH average.

The numbers should be interesting. Calculating over a whole season should give me a good idea of my average fuel usage.
