Rubber slinger rings are commonly overlooked during water pump work, but a worn or missing ring can allow water and debris to behave differently around the pump housing area.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eInstallation Notes\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eInstall the ring in the correct position on the driveshaft above the water pump housing, following the Mercury service manual and parts diagram for the exact gearcase.
