How to Replace a Seadoo GTX Impeller
A damaged Seadoo GTX impeller will need to be replaced, typically because a small stone has made it past the protective grate and into the propulsion system. Even a minor change in the surface of the impeller will have a significant impact on top speed and acceleration. If the impeller is damaged, you will need to purchase a new one as fixing a broken impeller is generally more expensive. With a few common tools, you can replace the impeller in a day.
