It is made for boat owners and marine mechanics who need a reliable replacement for a leaking or seized pump. The assembly cross-references MerCruiser P\/N 46-8M0139996, so it drops into the same mounting location as the original unit.\u003c\/p\u003e\u003ch4\u003eBuilt For Performance\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eComplete pump assembly with housing, impeller, and seal already fitted\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant housing built for continuous raw water exposure\u003c\/li\u003e\n\u003cli\u003eFlexible impeller that keeps flow steady across the RPM range\u003c\/li\u003e\n\u003cli\u003ePrecision-machined bore for a proper seal against water bypass\u003c\/li\u003e\n\u003cli\u003eDirect mounting match to the MerCruiser pump bracket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eOn-The-Job Use\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReplacing a raw water pump that leaks or stops priming\u003c\/li\u003e\n\u003cli\u003eScheduled impeller service on sterndrive and inboard setups\u003c\/li\u003e\n\u003cli\u003eKeeping coolant temperatures stable during long runs\u003c\/li\u003e\n\u003cli\u003eSeasonal maintenance before launching for the year\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 Number(s)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e46-8M0139996\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSea water (raw water) pump assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMarine engine cooling\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible Brand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003efor MerCruiser\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 Does this sea water pump assembly come with the impeller installed? \u003cstrong\u003eA:\u003c\/strong\u003e Yes, the assembly ships complete with the impeller and seals in place, so it is a bolt-on replacement.
