Supercharger washer confusion

[pro10is]

Back in July I purchased a Riva Heavy-duty Supercharger Clutch Washer '08 255/215 Kit for my 2008 Sea Doo Speedster 150 215HP. I now finally have a chance to install it off season, however there is a problem. Both new clutch washers are the same inner diameter which is supposed to be correct for the 2008 model year. However my supercharger appears to require one large inner diameter washer and one smaller inner diameter washer as was specified for pre-2008 model years because my OEM ceramic clutch washers have one large inner diameter washer and one smaller inner diameter washer.

I'm the original owner of this boat which was purchased new and unused last year as a 2008 leftover so the supercharger is OEM stock. It appears I may have 2007 spec supercharger. It looks to me that Sea Doo may have built early 2008 model year boats with the pre-2008 spec SC.

Can anyone confirm this? Do I now need to order the '06-'07 Riva SC clutch kit?

Thanks.

The reason for this is the 08 Sport Boats actually used the 07 style clutch assembly
