What is the RPM threshold for when this part is required/necessary? I've heard 8500, but I would think that also depends of how many times the rider bounces up to that RPM (IE wave jumping, etc.). Thanks!
Any time the factory rev limit is increased, this shaft is a good addition to maintain reliability. Sustained RPM over 8000 with higher peaks can cause the stock shaft to fail. This upgraded shaft is a necessity when using an aftermarket supercharger impeller due to the increased stress on the system.

+Edgardo Emralino It would be nice if we could offer this part for less but it’s very expensive to manufacture. The shafts are built to our specification in Japan by HKS which is the original manufacturer of the Yamaha OEM supercharger. HKS holds the shafts to very high tolerances due to the high RPM and performance requirement. Also the addition of the external oil feed system adds complexity to the manufacturing process. This shaft is used by the world’s top PWC racing teams and has a great record of reliable performance.
That's really not a bad price at all if you know the manufacturing processes to generate what you're getting. That one piece supercharger shaft is NOT cheap at all to produce, especially being a billet piece.
@@Anterisix how much they get paid per hr in Japan do u have a idea?????? they are NOT made in Usa... cmon 500 for something that max could cost in japan is 25-50$.... Boating parts are so f ridiculous.

installed a few of these its worth it if your running 8000 rpms it even sound smoother at a idle
just bought one . had no idea how to connect the oil line
Didn't know if takes oil from oil pressure sensor port
Thank you for the info ❤
Riva Yamaha should do a install videos on there products.
Very nice, how much is this?
