This video will guide you through the removal and re-installation of the impellers on a Yamaha jetboat with either 1 or 2 of the 1.8L engines. This particular job was done on a 2018 Yamaha 212x. The new impellers are the 6CW01 that have also been re-pitched for better performance at higher elevations. The end result of the swap was about a gain of 1000 RPM's, small (3mph) gain on the top end and lots more power out of the hole and pulling out of corners. Use part WR014H to hold the shaft.
