I took the Jetski out on a new-to-me lake last summer, got to the end, and turned around to head back. 5 minutes into the ride back, I had to switch over to reserve. Thinking I would conserve fuel I backed off to about half speed. 15 minutes later I was out. 3 hours later I had swam the boat back to dock.

Someone told me 2-stroke motors want to run at near full-throttle to get the most power out of the fuel. I'm not sure what is most efficient, and haven't seen a BSFC for 2-strokes.

All that said, I think reducing weight is probably most important if you can't change the hull shape.
