jet-drive outboards

[jamie7117]

anybody have much experience with jet-drive outboards?

how much for 50-60hp?

i see some boats have a channel in the bottom of the boat, so the outboard can sit higher in the water, does the channel extend the length of the boat?

god, i can't wait for the boat show!

Jet drives are really nice for flats and river fishing, but they aren't very efficient. As far as tunnel hulls, different Manufacturers have different offerings. A buddy of mine and I are just completing work on an Alumacraft v bow 1860 tunnel hull. The tunnel extends about 1/3 the way up the hull. (only about 2' of the boat is in the water on plane) Even with a short shaft 50HP, the cavitation plate is lower than the transom. We installed a Hydraulic jack plate so the motor can be lifted vertically, while maintaining the proper trim angle. Now, when lifted all the way, only about 1" of skeg is below the transom, and the tunnel will provide the water needed for propulsion and cooling. Hopefully the maiden voyage will be this weekend, I'll let you know how this works...............

I've also have been checking into a jet drive for my 90 horse. Some of the things I've read and been told are a power jack plate to raise and low the engine, it also sets the jet back to pick up cleaner water. You lose some where around a 1/3 of your HP. You probably could figure the same for gas mileage. I read where you don't want a boat with a complete flat bottom, some vee in the hull helps with steering. Also there is a learning curve in the handling of your boat with a jet motor. As for price I was told I could get a unit for my 90 HP, for about $2500. I would also put a kicker for some fine manuvering in tight quarters and trolling. Also if your doing a conversion from prop motor to jet drive unit, you will need to be careful as to not exceed the manufacturs recommend rpm when running the jet. Hope this helps.

All I can tell you all is try a jet drive before you buy ,I did and I don't own one ,I think if you used it as a kicker it would be ok or for short runs,seems like a lot of lost HP.
