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.

Re: Fuel Usage
In $CDN I put in just over $1500 this season. Our marina averaged about $1.15/Litre (includes members discount) this season so that equates to just over 1300 litres (433 US gallons). Between my two operation speeds I average about 10 gallons per hour, average speed of the two is about 10 nm/h. So, I am burning right around 1 gallon / NM.
I still wish our season was longer!!!!

Re: Fuel Usage
I added $3200 CAD of fuel this year and still have 1/4 tank. I did log almost 1100NM on my GPS and just under 100hrs on my mains. I also put 300hrs on my genny.
Fuel is the cheapest part of boating!

Re: Fuel Usage
Agree completely. Even in the go fast. For some reason people don't believe it.

Re: Fuel Usage
Some say that fuel is the cheapest part of boating. If you own your boat free and clear then fuel becomes a larger portion of the expense pie. This season I spent $1935.08 on fuel. If I were to remove my transmission repair from my costs this season fuel would be my biggest expense. I paid $1700.00 for my summer dockage. Not sure what my winter storage cost will be as I have not pulled yet.
This year my biggest expense was my transmission rebuild. Next season if I have no further mechanical issues fuel will most likely be my biggest expense. I am tentatively planning my next seasons cruising and it is somewhat ambitious so again with no unplanned mechanical problems fuel could be my biggest expense next season.

Re: Fuel Usage
For me , I think that , "fuel is the cheapest part of boating", would be ultimately dependant on how how big your boat is and the value of it.
Over the years, for me on a number of boats of different sizes, that approx 1 NMPG number seems to show up over and over....

FWIW.....The above is just my opinion.

Re: Fuel Usage
I'm $8000 per year (including shrink wrap). Annual maintenance/servicing - oil changes (mains and genny), racors, impellers = $2500, other maintenance items $1500. So fuel always ends up cheapest for me.
