Jet Drive on a C-Dory?

Does anyone have any experience using an outboard jetdrive on a C-Dory 22?

I use to own a CD22 a few year back - BlueEcho. It was fitted with twin 40HP Hondas. Great set-up. My wife got pregnant and we needed an new SUV more than the boat, so I sold BlueEcho to some nice people up in Maryland. Well my kids are a bit older and I am back in the market for a CD. However I have moved from the Texas Gulf Coast to Virginia. I plan to use the boat mostly in the Potomac River, especially the upper end were depths often drop to less than 2 feet. So this time around I am considering an outboard jet drive. Honda makes one based on the 90HP power head. Does anyone have any feedback on how well this set-up will work?

Thanks
 
most jet boats are made for a jet engine and are designed to turn with a jet. This is done with strakes or hard chines on the bottom of the hull. the c-dory does not have much in the way of strakes and only a small hard chine. I dont know if its enough to make it safe. the jet its self does a lot of the turning but the starkes keep it from sliding out of control. hope this helps.
 
Weight of the c-dory is another factor, there are some great boats out there designed around the jet. Alumacraft, Weldcraft, Predator Jon, North River, Wooldridge, Duckworth and at least a hundred others make great jet boats.

I suspect that you will not be happy with the proformance of the CD 22 with a jet lower unit. I run my boats in 18" of water, with motors up, to get over a sand bar. When running regularly in shallow water, I will usually use a kicker, since the boat is at displacement speed, you can keep the prop up above the bottom of the hull.

I would not run a C Dory at planing speed in 2 feet of water--too much risk of hull damage, as well as jet drive damage, plus the sand and gravel pick up from the jet unit. But these are personal feelings.
 
Here is a bracket that would allow the prop drive to do almost as well as a jet pump in shallow water. And still have all the great advantages of a prop outboard. The benefit here is that when you raise and lower the engine the prop and thrust angle remain parallel to the boats bottom. Thus giving much better control.
