I was up in Cordova, Alaska a few years ago and saw aluminum commercial work
boats that were powered by GM gasoline V8s with jet drives. I asked why they
used them in the ocean because they are not as fuel efficient as a propeller
drive. They said because they work nets right in close to the shallows and
they had less damage with a jet drives. Outboard jets have about 30% lose of
power while inboard jet drives have about 15%.

If you don't have a reason (running in shallow water) for a jet drive I
would stay away from them.

Does anyone here have any experience with a 250hp mercruiser/cummins
jet/sterndrive. Would it be a good candidate to repower a 31' X 12'
aluminum workboat. What are the pros/cons of a jetdrive vs a prop
sterndrive.
