I got a 1989 js550 and have no clue what kinda millage they get. How many hours on the water is average?

Your mileage may vary

30 miles at full throttle.

About 1 gal/hour is what I have experiened.

Understanding how far you can go on your reserve is a good piece of data if you always ski the same lake so you do not go past that point when close to the reserve.
