I have a 2000 XL800 that runs great...strong motor but it cavitates at 15 mph and around 5000 rpm. It continues to cavitate unless I let off the throttle and slowly throttle past the 15mph. I changed the impeller twice, a Solas then back to a stock, three different wear rings including a new stainless one, pulled the engine to verify the coupler from the shaft to the motor was in tact and not spinning. The grate and other components were sealed properly and the only thing I didn’t change was the impeller duct. Can the impeller duct make it cavitates? I’m looking for suggestions to eliminate this cavitation.
Thanks

Did you ever find out what this is?
I have a Yamaha xl800 and have the same issue.
I fount it got slightly better when I turned right and accelerated past 15mph for some reason.
I too replaced my impeller, remanufactured entire engine + more with no luck fixing it.

I still have not fixed this issue. Have you?
