Complete gasket kit for Ossa engine rebuilds on specified 1971-1977 MAR and Explorer 250 models using the small diameter crankshaft. The kit includes all gaskets, seals, O-rings and the head gasket. On Explorer models, Ossa used two different centre case gaskets depending on crankshaft style; OW-CGK-301 is for the older small diameter crank, while the newer large diameter crank uses OW-CGK-302. In many cases, the crankcases must be split to confirm which Explorer kit is required.
