    I have one, I really couldn't tell you what a difference it makes over a stock one or other one because I bought it with it, I am sure someone else could though.

    Well, I'm still selling them after 11 years, so they must be selling. I am in the process of designing a new one for the 1800 pumps, which will be my 4th yamaha design.

    Rampage, take the shuttle out and go for a ride, then put it back in and see what the difference is.

    The shuttle is just the plastic part that slides in and out. If you got the wrench that came with the AAT, then you can remove the shuttle in less than 30 seconds. It's just a long allen wrench. no need to take anything apart.

    I've bought two for the GP and GPR boats from Da Wolf. They both work as advertised.

    If you pull the shuttle out, you will loose about 1 to 1.5mph with an increase in RPM, reinstall the shuttle and get the speed back with the same loss in RPM.

    WetWolf, about a year or more ago I had tried repeatedly to contact you by email and phone. I was interested in what your AAT could do for my 08 Yamaha 212SS jet boat. I never heard a response from you and I have never found anyone who tried it on the Yamaha boats. I belong to a Yamaha jet boat forum and there are a ton of people who are interested in performance on these boats. The non-HO 210 models seem to be really underpowered and I'm sure many owners would be interested in your product if it would help them. Feel free to PM or email me if you are interested in this.

    ...sorry for derailing.
