Keeping that gap in spec lets the wear ring for Yamaha GP 800 push water through the nozzle rather than letting it recirculate, which protects acceleration and top speed. It is aimed at owners servicing a 1998-2000 GP 800 pump after wear, impeller swap, or debris damage.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e144mm inner diameter matches the stock pump bore for correct impeller clearance\u003c\/li\u003e\n\u003cli\u003eReplaces a grooved or eroded ring that has opened up clearance over time\u003c\/li\u003e\n\u003cli\u003eHelps limit cavitation and ventilation during hard launches\u003c\/li\u003e\n\u003cli\u003eDrops into the pump housing location without machining\u003c\/li\u003e\n\u003cli\u003eWorks in both fresh and salt water personal watercraft\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFits These Machines\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003efor Yamaha GP 800, 1998\u003c\/li\u003e\n\u003cli\u003efor Yamaha GP 800, 1999\u003c\/li\u003e\n\u003cli\u003efor Yamaha GP 800, 2000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePump rebuilds after impeller replacement\u003c\/li\u003e\n\u003cli\u003eScheduled driveline service on GP 800 hulls\u003c\/li\u003e\n\u003cli\u003eRecovering performance after sand, gravel, or debris passes through the pump\u003c\/li\u003e\n\u003cli\u003eRecreational riding in fresh and salt water\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 GP 800, 1998-2000\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 How do I know the wear ring needs replacing? \u003cstrong\u003eA:\u003c\/strong\u003e A ring with visible grooves, scoring, or a loose impeller gap usually causes cavitation and slower acceleration.
