GAS - HOW MUCH YOU GOT?

Recommended Posts

We ski a course exclusively with our boat. I can think of 2 times we used our boat this summer for something other than 6 passes to a set. Mostly me skiing, but my wife skied on our boat in the course, and me and a buddy split time between my boat and his (so it is a wash the times he skied on mine if I consider the times I skied on his).

 

Just added up the summer receipts and found that we burn 511.278 GALLONS of non-ethanol 92 Octane..................

 

I think this is up a hundred gallons from last year. AND I HAVE TO CONSIDER that I joined a club this year and didn't include my gas from there, and I spent a week in California skiing 2 sets daily.

 

I don't add up the dollar amount on purpose, I just don't want to know............

@GOODESkier, based on my ski partner's boat and my boat (both 196) you must have skied over 500 sets. Assuming that you don't ski year round (you totaled up your season usage) even if you ski 8 months that's over two sets a day every day for the eight months. Are you sure someone's not stealing gas from your boat?

@OB and @Wish I can only get non-ethanol in 92 octane around here. I vowed a few years ago that for the chump change it would cost to run 92, if I could afford to ski, I could afford to run 92 Non-Ethanol. I run it in all my toys. Cars and Trucks get the ethanol 89, but snowmobiles, motorcycles, and boats get non ethanol (and lawn mowers and weed eaters and such).

 

@LeonL I ski 2-3 sets daily from May - November. Boat has 500 hours of course skiing in 3 years from just me and my wife (and my pull trades with my buddy, but that is a wash in the end with the hours and the gas).

I only keep track so I can get the gas tax back at the end of the season.

 

YES, addiction! Fortunately I live right by my course and my launch is 1/10 of a mile from my house. NOW snowmobiling is a different story, I burn way more gas in my truck than actually snowmobiling. Curse of the mountains.

My experience on fuel usage is for 2 skiers / 2 sets / 16 passes per set = 4-5 gallons of fuel use depending on specific boat & the 196 was the thirstiest one. That is using regular gas w/ ethanol.

 

To suck down that amount of fuel, you ski a lot. I would suggest you can, if you choose to, save some money by using regular octane fuel and running the dreaded ethanol fuel until the last few seasonal sets so you purge the alcohol out with ethanol free fuel. You might also consider if you are set on running 92 octane fuel, bumping you your ignition timing as the higher octane is basically burning later than optimum and robbing you of a bit of power and fuel economy and heating up the exhaust a bit more than needed. Compression ratio for that boat should be around 9.5:1 and certainly not over 10:1, regular gas will work just fine at 160 degree engine water temps.

@DW I am a NON-ETHANOL guy......It only saves me 15 cents per gallon............ on 511 gallons I over paid by about ...... $75.

 

Not messing with my timing and other things. I would love to know the difference in exhaust gas temp for the 87-92 octane range. Since on my snowmobile with a turbo, it is a pretty small difference, can't image it is much on a boat.......
