Impellers with dual engines...

[PburgDooey]

I'm sure this has come up before, but I cant find any info.

With twin engines, are the impellers the same? Or, do they require a different pitch to neutralize the rotation?

seeing that you have a 98, they are the same pitch. Yamaha jetboats usually have different pitch impellers for the starboard and Port engines.

He is correct. Sea doo fixes that rotation issue by using a different diameter nozzle on one of the pump outlet. Look and you will see the difference.
