the jet will use more gas a prop. so unless a jet is wanted for its
advantages, which it has like:

- runs shallow
- boat can break (as in stop)
- doesnt hack up people
- fun to drive

so if you do not need any of that, then get a prop. Stay away from
rotax jets, as others said they are high maintenance.

If you decide on a jet then get a boat which has a MERCURY SPORTJET
with a 200 HP or 250 HP OPTIMAX. These will get very good mileage. My
boat is 19 foot with a 200 Optimax Jet and cruises with 2 people and
light gear at 5.8 MPG ! Cant complain about that
