Does anyone know of a source for a small, low power/speed jet drive? Power would be inboard up to 25 hp. I am thinking about building a Redwing 21 for use in quite shallow areas - marsh and backwaters. I thought that a small jet drive would be better than a prop. Thoughts?

There's a pacific northwest outfit with a name like Traktor that makes a high volume low speed jet. I don't know if they make anything for that low a horsepower but given the light application, it might work anyway.

Here's a page full of links to jet drive manufacturers, including small drives:

I've used Evinrude/Johnson jet outboards in the 25HP range, so somebody must make the pumps.

try Berkeley Pumps (Jet Drive pumps) in California.....and another whose name slips me that made the original pumps for those &^%$#@$%#^&*(*&^%Jet skeet targets.

Wilfred sorry to say I can't help with the jet drive but I am just about to start building a red wing 21 I am going to use a 4 stroke honda 25 hp.We should keep in touch and help each other over the rough spots.

tongue.gif {jealousy} I'd kill for a 25 Honda 4-stroke. What's it going to set you back? Maybe we could get a break on 2?

Donn I have no idea what they cost it will be at least a year or more before I need it.I see from your post your a long island boy like me.I am from southold and have spent many happy hours on great south bay and peconic bay.My father in law owned rays boat shop in greenport.I worked with him for sevral years befor I got into tv .we built a 40 foot sloop and 2 35 foot sport fishermans while I was working with him.that area has some real nice boating I really miss it.

Cabela's has a Nissan 25, 4-stroke for $2700, delivered. Nissan (ne: Datsun) make great motors. I have 2 of them in Loon.
Videoguy...I love the Peconic. Biggest fluke anywhere, and an amazing history of family-sized commercial fishing..dragging oysters under sail, etc..
Why would you move from Southold to NJ??

Well, I was estimating, based on Mercury catalog prices ...
Careful Donnwest admitting you have a Nissan motor around here ;)
You could start the whole American vs. Japanese thing ... :eek:
Not with me, though, I have a 65-horse Suzuki on a skiff and love it.

I guess the Jet Drive business must be real good. I am building a 24" Ken Hankinson design for use on Cape Cod bay, and a jet drive would be a very viable alternative to the I/O Mercruiser. I sent of enquiries both by email and faxed in spec sheets 2 weeks ago and I didn't hear from one supplier. :mad:

Thanks for the replies. I will start to investigate the leads you have provided me.
A tip on the Nissan 4 stroke motors: Look at Tohatsu 4 strokes; Tohatsu makes the four strokes for Nissan and the Tohatsu motors are the same but cheaper. I bought a Tohatsu last year - great motor.

Probably silly idea:
I note that PWC's or whatever have a peculiar tendency to collide with solid objects. This generally crumples the F*****G**** and the operator and leaves the mechanicals intact. Might the mechanical bits of a crumpled PWC be a reasonable solution here?

After doing some reserch on jet drives, I've found them to be VERY inefficiant as to fuel milage. Check some of the websites on jetdrive jon boats.

Hi
Just a thought. I use a aluminum jetboat at work to travel around our reservoir and up to tributary streams. If you are in shallow water you have to be moving. If you slow down or stop you will suck up half the river or marsh bottom. It's not always easy to clean the pump out to get going again. They also will suck up lost of aquatic vegitation when going slow. You also have very little control at low speed.

The jetsky drivers in my bay have the same problem....HAHAHA... they slow down to rest, and fill their pumps with eel grass, and we run 'em down and swamp em with our wakes.
Anybody makin wooden jetskys?

I think you'd be better off with a prop. As big as you can turn and keep it above the keel. If you have a shallow keel, you'll need a skag to protect from grounding. A jet has almost no stall speed power. A prop with a good skag/keel can littarly blow a whole under your boat.
Another consideration is cooling the engine. Many jet systems divert pump flow to cool the engine. If you are sucking mud and oyster shells, that is going to crap the engine up pretty quick.
A good inboard with prop should have a nice big, easy to clean strainer for the engine cooling water.
I live in SW Florida where it is shallow everywhere. A pair of 20 x 20 four blades made my wet slip from six inches at low tide to four feet in just a few weeks. Yep! I had to clean my strainers pretty often. I had to take several swims to get rope and stuff out of my wheels.
I am not familiar with the design of your 21 ft boat, but I should hope, if the bottom is shallow enough to hit, it is shallow enough to jump out and push.
