I have two 2021 3up Sparks. I took them 72 miles on smooth water a few days ago but we were on fumes when we arrived. One took 7.44 gallons to fill up to 3 inches below the cap and the other took 7.6. Since the capacity is 7.9, I suspect I had about 8.3 to 8.5 with the filler hose topped off. I didn't run WOT the entire way. I stayed between 35 and 45 because I knew it would be close.Can anyone give me an idea of the WOT range. I will be on the river and just need a good guess-t-mate.
I have the 90Hp and will probibly keep it in Sport mode at 3/4 to full throttle.
Also, looking for good auxillery gas tank ideas.
