I have no experience with that particular jet drive. However I have two
160HP yamaha jets on my boat. The 2 biggest drawbacks of a jetdrive a

1) Getting crud caught on the pump intake grate. Usually it only happens at
slow speed, and is generally easy to clear. I've run my new boat for about
12 hours, and it's only happened once.
2) Slow speed handling...Without a big stern drive or a proper rudder in the
water, it's a different animal at slow speeds. I know a guy that fabs fins
to attach to the jet nozzle that GREATLY improves the slow speed handling.
If you need it, I'll get the link to you.

I really love my jet drive boat. Good luck with your decision.

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.
