This full gasket and seal kit provides all necessary sealing components for a complete engine rebuild or installation on Sea-Doo watercraft equipped with the Rotax 787 (782cc) engine series, marketed as the 800 platform.

Contents include cylinder head gaskets, cylinder base gaskets (0.6 mm thickness), exhaust manifold and pipe gaskets, intake and rotary valve gaskets, crankshaft outer oil seals (PTO and MAG side), RAVE valve gaskets, and all required O-rings for cooling, lubrication, and fuel passages.
