NEW Genuine OEM Yamaha Cap Case F1W-U591C-01-00 & Packing Case F1W-U591D-00-00. 

NOTE: The Packing Case gasket will need to be stretched and pressed into the recess in the cap in order for this to fit.  This is part of Yamaha's design to keep the gasket in place in the cap.

This cap and gasket fit many Yamaha PWC models.

These are genuine OEM Yamaha factory original replacement parts, not aftermarket.
