We have been in contact with Skat Trak to develop an Impeller for the Sea Doo and at the same time make one for the Yamaha. The Sea Doo Impeller was sent to Naples to be used in the recent Flyboard Competition and was fine tuned by non other than Malvin Quinones.
The Sea Doo impeller fits in the 161mm pump and does not require the change of the wear ring. The Yamaha is also manufactured to fit the 160mm Pump. Both have a 4-blade inducer. They can bothe be manufactured with the sam pitch with a different diameter to fit in the 158mm Sea Doo Pumps.
