A lot of none boat owners don't have a clue how much gas most boats drink. Hell I'm even shocker how much fuel my little 7.5hp kicker drinks. I'm sure at 2mph is almost as much as the 115 main runs through.....but it's so nice not to have bags out to slow down, it's nice to be able to talk and yell, and it's nice to be able to let go of the wheel to help net a fish or a tangle and have the boat do an instant 360.
