AA Impeller for Sea Doo Switch 100/130/170hp

AA custom Impeller for 2022+ Sea Doo Switch 100/130/170hp models High quality custom stainless steel 155mm impeller We tested many different impeller designs, pitches, and found this one is the best possible for all around performance, and a great OEM replacement. Higher RPM did not seem to net any real performance gains, and only increased chances of cavitation. So while many think running higher RPM is key, for these models, it did not prove to be the case. Impeller is designed to have the same peak RPM as the OEM impeller with +/- 100 RPM Rugged impeller to be pitched for needed RPM changes where OEM is too soft to pitch with consistency. While all impellers can be damaged, this is a heavy duty stainless design will resist damage better than the soft OEM one. We always suggest a new wear ring when installing a new impeller. We always keep with and suggest plastic. They are much easier to change out if you have an issue, and we believe it's best to have a weak spot. Since the AA impeller is much stronger, it's important for the wear ring to give out. We've used both, and won't go back to a stainless ring. Part number 123-1010
