Hi Supraman,
It is a 2001 S22, not an SX22 with the built in hard tanks. It is a V-Drive, has a small fill/empty switch above the throttle lever. It came with 3 bags, 2 smaller blue ones, and 1 massive grey one, that almost seems like a bag within a larger sack. The grey one doesn't look like there's any way it would fit in any of the rear compartments, and the blue ones don't look like they'd fit in the compartments to the side of the motor, but also too small to fit in the rear ski locker. The pump is mounted against the motor/ski locker dividing wall, to the bottom right when facing backwards, and there is a hole cut to the ski locker for tubing to run. Please see attached photos, I'm really having trouble piecing this puzzle together.
Thanks!
