They are separate sellers, both have records, both were used in fresh waters, but neither had their superchargers rebuilt before.
The dealer told them at 200hr and not 100hr.
I would still rebuild the SC after the purchase and before the 200hr.
I thought they stopped using ceramic washers in models 2008 and over!
I bought a 2008 and it had ceramic washers in the supercharger. The early 2008's had ceramic washers, so be very careful. I got lucky and caught (rebuilt the supercharger at 55 hours) before they self imploded.
