Drake jets were made in very limited and a couple different "maturations" ,There Beefy and strong and When they work they work pretty well , because of the low production numbers (highest serial number we've seen was 200 ish) There almost no "spares" anywhere except used , some internal parts are bearing and seal house items, I actually had Three of these till yesterday but sold one with a trim unit in the afternoon, We have swapped out several for Berkeley style jets over the years Good Luck Tom

How much is the boat? What condition is everything else in? Trailer? Title?
Its fair shape, $1500 needs new interior but hull is good ,trailer is good need to check the motor to see if it turns over. But all in all its fair. Just not a fan of the 455, and didn't know anythink about the drake pumps.

Crazy,

My dad had a '75 Omega hull. 18 footer with the red/orange metal flake and he had a Drake jet drive. I NEVER saw another one in my life! LOL

I fully understand that the Berkeley design is the best- And then you can get into arguments about which version is better- American Turbine, Aggressor, Dominator.........But, I find any of the different pump designs interesting. I wish I could see more photos and diagrams of the different ones...Everything you want is out there for the Berk style, but what about this Drake, the Chryco, the Panther and, the holy grail of (Jet drive)snipe hunting, the Mercury jet(Circa 1968-70)......It's just interesting to see how different designs solved problems, etc. If any of you ever see any of these, if you can afford to, save 'em, and either way, take some pics and post them. Update- I also remember TWO different stern-drive style jet drives- One was from Rockwell International, and one was a different version of that design- The whole thing mounted on the stern, and the water came up and did a loop, then exited the nozzle up higher- Wildly different- probably not very efficient, tho!

And Tom, thanks for the few pics of the drake- I've only seen a few other pics- It may have been on the Vintage Jet boat site or the Real Jet boat site....I can't remember(I hate getting old!).....

If you ever get a chance, take some pics of that pump....I believe somewhere I have a xerox of a Trailer Boats magazine test of the MercCruiser jet- Now I'm gonna have to go digging for that test. And that Dale Drake connection.....WOW! I had no idea....The history of that Drake/Offy engine is absolutely amazing.

Just made a one off wear ring for a Mercury Jet , very similar to your "basic" Berkeley , Drakes more closely resemble Jacuzzi WJs in build and design , I don't think Drakes Jet numbers exceeded production much past #200 ish and within that there were a couple maturations , including a "trim" , Have a couple in the JBP "museum" , OK performers , strong and beefy , cant give them away ;)


Heres another Swap or two

That's some nice info- I can't seem to save it or print it- I may have to see a (Computer expert) friend. Thanks! I can't seem to find the pics of that Rockwell or Rocketdyne jet drive- It was really different; It mounted outside on the transom...The intake was at the trailing edge of the transom, and then the tube swung up and forward, going thru the impeller forward, and then swinging back around to exhaust to the rear. There was another one that looked more "Production ready", all white smooth castings, and it exhausted thru seven individual nozzles.

I doubt if they were very efficient, but they were definitely different!

Yes Rigger! That was the "Military style" one I saw at Teshio's site. But I remember one that was painted white in a magazine- It had a gracefully curved intake and the impeller faced backwards so the water went thru going forward, then curved around in seven exhaust nozzles- Never saw or heard anything about it ever since. It was interesting looking tho. Thanks for posting those pics...I couldn't remember the manufacturers name- I knew it was an Aircraft company tho.
