Sea-Doo GT SP 580 Complete Gasket Kit
Complete gasket kit for the Sea-Doo GT 580 and SP 580 personal watercraft equipped with the Rotax 587 engine displacing 580cc in a 2-stroke 2-cylinder inline twin configuration with a 76mm bore and 64mm stroke featuring CDI ignition and rotary valve induction. This comprehensive gasket kit includes all the gaskets needed for a complete engine rebuild including head gaskets base gaskets exhaust gaskets and crankcase gaskets. The GT 580 and SP 580 models feature the earlier yellow engine block variant of the Rotax 587 producing approximately 55 horsepower and the water cooled 2-stroke design operates under severe thermal cycling which degrades gasket materials over time. Replacing all gaskets during an engine rebuild ensures proper sealing at every junction and prevents compression and coolant leaks. Always clean all mating surfaces thoroughly before installing new gaskets and torque all fasteners to factory specification for a reliable seal.
