OK so I have an idea......OK get that scared look off your face, I have an old jet ski motor is shot but pump is good. Measures 16 inches long by about 7 inches wide, I wanna mount it half in and out of the rear of the body on back and use it as a drive for the water travel on this terra jet. BUT I need to find a way to power the unit as its a complete 90 degrees off my main motor shaft, plus you can't run the unit out of the water, thinking either electric of a small gas motor, doesn't need the power that the normal jet ski does, just needs to move me faster then the normal 2-4 MPH that the tires produce. Thoughts, ideas am I crazy?
