Back in 1994, My friend Chris and I  began looking for a way to get more out of the jet pump of a pwc. I was service manager at a Polaris dealer, and he was service manager at the Yamaha shop, so we had lots of pwc around to play with. We knew that there was a way to get more out of the jet pump of a pwc and put down all sorts of designs on paper Most of them mechanically actuated iris type openings meant to change the size of the pump nozzle according to craft needs. One weekend, while my parents were visiting, my dad, while looking at my designs, made the suggestion that I reduce the nozzle from the inside. I drew up some different designs of moving tail cones, the only problem was how to actuate the center piece and make it move back and forth. The tailcone was put on the backburner of my brain while I attended to life for awhile. 
In 1997 I was working at a hydraulic machine shop. One day while repairing a bottle jack, the little light went on over my head. (IDEA!!!) The shifting tailcone could be actuated in much the same way as the jack. A simple hydraulic displacement cylinder, and it could be actuated by water pressure inside the pump. Working at a machine shop made it quite easy to build a prototype and since the shop had CNC machines, building them in quantity was also an option. Initial testing was done with 2 SL1050s. Side by side testing showed an increase in top speed. I knew it worked, now I just had to think up a catchy name for it.....

Heres a little AAT history for you folks.
A pic of the stock Polaris cone on the left.

The 1st prototype, and pretty much the only prototype. It used a mikuni main jet in the orifice for tuning. you had to pull the exit nozzle to change the thing. A real pain in the butt, but hey , it was a prototype.

The 1st production model. It used a set screw that was accessible from the rear of the nozzle for controlling the size of the inlet orifice and you tuned it with the same wrench that you used to change the shuttles.

The 2nd production model, which just used shuttle length for tuning which is really the way it was designed to work anyways. We changed the shuttle bolt to a beefier model to reduce loss and breakage during this production run.

And our newest unit. I guess the AAT3! Notice how the main body keeps getting smaller.., And the shuttles are bigger, which allows more more total volume change within the bowl of the pump and a little bit more control.

As soon As I can, I will update this page to reflect the changes to the AAT for 2006




About Wet Wolf Technologies - Bruce Wolford, Owner and Inventor of the Adjust-A-Thrust. 

I began riding dirt bikes when I was 10 years old. My first bike was a Honda CB100.  From the first jump on the kickstarter, I was hooked. I hung around the only bike shop in our little town, had to ride 7 or 8 miles in the dirt to get there. I would ride for hours after school and on the weekends in the deserts of New Mexico. My second bike was a Triumph 500, I still own it. My senior year in high school (1982), our family moved to Kennewick, Washington. My riding in the desert continued.... I tried my hand at motocross for a while, but I broke a lot of bones doing it.  I managed to secure employment as a salesman at a motorcycle accessory shop in Kennewick. It didn't pay much, but I was able to afford handlebars, grips, levers, and pistons. Lots of pistons. This was the beginning of a long relationship with the internal combustion engine.

On to college, Central Washington University, Ellensburg WA. Once again, I found a job at one of the bike shops in town. I considered this to be a step up as I was put in charge of assembling and set-up of new machines, and fix-up of the used machines. I also got to put in a little saddle time on snowmobiles. The owner of the shop bought out a small motorcycle parts distribution company, and my next job was a traveling sales rep. I drove a box truck crammed full of goodies (tires, chains, oils, bars, grips, etc,) all over eastern WA, a little bit of Oregon, and a little bit of Idaho. During one of my visits to Spokane WA, I was mildly surprised to meet one of the guys that I had worked with in Kennewick, he was working at a shop, and flat track racing on thursday nights. I tried flat tracking and found out that it was kind of fun going sideways, hooked again. I rearranged my driving schedule so that I could be in Spokane every thursday to go racing. Flat track racing seemed quite mild compared to the rigors of motocross, and if you did fall off, you were closer to the ground to begin with. I was offered a job in Spokane as a mechanic at one of the bike shops that I used to sell parts to, and off I went.

Once in Spokane, it didn't take long for me to start moving around to the different shops until I found a cozy job as Service Manager at a local Polaris dealership. When I didn't actually have to be running the service dept, I found time to build fast snowmobiles, and fast motorcycles. We were one of the first shops in the area to have a  Land and Sea Dyno. My best friend and next door neighbor, Chris,  was service manager of the local Yamaha shop, and we have spent many hours riding sleds, dirt bikes and ATVs around the Inland Northwest. 

In 1991, I took my first ride on a Super Jet, damn was it fun, ever since then, I have been hooked on PWC. I have been involved in PWC racing since 1994. I served as race director for the Inland Northwest PWC Association for 5 years. I am also the PWC race director for Northwest Water Competition, an APBA affiliated PWC race promoter. Northwest Water Competition is also affiliated with the NBRA. we run races , many hydros and classic ski boats, you've seen them before they're the ones with the big V8's sticking out of the back and loud exhaust blasting across your local lake at 80 or 90 mi. an hour.

As PWC race director, I spend most of my days standing out on the scaffolding in the water.  Starting races , and watching races , and getting burned by the sun.  At the Hydro races.  I am the main course Marshall.  I spend my time sitting on the middle of the lake on the PWC roasting in the sun and waiting for a  Hydro to flip or a flat bottom boat to go over.  I spend most of my weekends during the spring and summer months on the water and loving every minute of it. During the winter, we ride the Spokane River when all the lakes freeze up.

I own a Polaris Hurricane, and a Yamaha Super Jet. I raced the hurricane until the sport class started going away.  Now I have the super jet, I'm still learning to ride that. Update on this one. I raced the cane last year (05) and did quite well, here's a pic of me out in the front. No Wonder they can't pass me!

More to come later.... my fingers are getting tired.
