On my moose hunt we ran at least 150 miles total mileage (both short trips and the long commute). We hauled an estimated 1000 lbs. Total fuel used: 7 gallons of fuel
The motor used was a Tohatsu 9.8 fourstroke lifted to the point of cavitation for the entire trip (but trimmed properly). I had brought 18 gallons of fuel and could have easily freighted two moose, people and gear in a series of three runs if I had to with this one boat and would have burnt 14 gallons of gas for an estimated 380 miles of river and lakes.
I say nay to jet boats,.........go grab an Esquif Cargo canoe You can bash it into anything, drag it across shallows, paddle it quietly, and burn minimal fuel. Yah just gotta get your balance so you can stand with a tiller extension.......and your going anywhere you need to, even if the water is 8 inches deep with a thousand pounds in the boat. If it gets shallower than that.......get out and pull the boat over the shallow spot, or.......if going down river.....lift the motor and pole.
A jet boat broke down where I was this year, so plugged up with weeds his motor wouldnt work.
