By holding that clearance tight, the wear ring for Yamaha SuperJet 650 helps the pump move water efficiently instead of recirculating it, which keeps hole shot and top-end speed consistent. It suits riders rebuilding a 1990-1993 SuperJet pump during routine service or after impeller damage.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e144mm inner diameter sizing matches the stock pump bore for consistent impeller clearance\u003c\/li\u003e\n\u003cli\u003eRestores lost thrust caused by a worn, grooved, or eroded original ring\u003c\/li\u003e\n\u003cli\u003eHelps reduce cavitation and ventilation under hard acceleration\u003c\/li\u003e\n\u003cli\u003eDirect-fit replacement for the pump housing location, no machining required\u003c\/li\u003e\n\u003cli\u003eSuits fresh and salt water personal watercraft use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Yamaha SuperJet 650, 1990\u003c\/li\u003e\n\u003cli\u003efor Yamaha SuperJet 650, 1991\u003c\/li\u003e\n\u003cli\u003efor Yamaha SuperJet 650, 1992\u003c\/li\u003e\n\u003cli\u003efor Yamaha SuperJet 650, 1993\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePump rebuilds after impeller replacement or debris damage\u003c\/li\u003e\n\u003cli\u003eRoutine driveline service on older SuperJet 650 hulls\u003c\/li\u003e\n\u003cli\u003eRestoring a machine used for freestyle and closed course riding\u003c\/li\u003e\n\u003cli\u003eFreshwater and saltwater recreational riding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eSpecs At A Glance\u003c\/h4\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eJet Pump Wear Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInner Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e144mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eYamaha SuperJet 650, 1990-1993\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch4\u003eGood To Know\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Why does impeller clearance matter on this wear ring? \u003cstrong\u003eA:\u003c\/strong\u003e Excessive clearance lets water slip past the impeller instead of being pushed out the nozzle, which shows up as slower acceleration and cavitation. Replacing the ring restores the tight running gap the pump was designed around.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e How do I confirm this ring fits my ski? \u003cstrong\u003eA:\u003c\/strong\u003e Check that your pump uses a 144mm bore wear ring and that your machine falls in the 1990-1993 SuperJet 650 range.
