Default Fuel economy of older jet boats

I've read that the jet boat's impeller system is about 30% less efficient
than a similarly powered outboard. Does that mean that a jet boat will get
beat by an outboard, or just use more gas?


The jet will have a lower top speed. It will burn more fuel at any and
all lower speeds.
