I got these from a rotax dealer since BMW only sells a WP kit which includes a shaft and impeller (mine were OK). The guy told me these were the new design rotax W/P seals, part number 230195. (old number 230196). http://www.crg-america.com/kart-part...20(FR%20DD2%20
They are used in a rotax racing kart engine (FR125). it has the same water pump design as the f650.
