This kit provides the key parts you need — impeller, wear plate, gasket, seal, impeller liner\/cup and housing — sized to fit many OMC Cobra engines from 2.3L through 7.5L. It’s a practical, OEM-style option for routine service, mid-season repairs, or prepping a boat for storage.\u003c\/p\u003e\n\n\u003ch3\u003eWhich engines and years does this GHmarine 984461 kit work with?\u003c\/h3\u003e\n\u003cp\u003eThis kit is designed specifically for OMC Cobra stern drive engines produced between 1986 and 1993, covering 2.3L through 7.5L displacements. It fits most Cobra variants in that range but excludes the 1990 2.3L and King Cobra models from 1992 onward.

Replacing these together ensures the pump seals correctly and delivers intended water flow, reducing the chance of repeat failures shortly after service.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eImpeller (777128) — moves cooling water through the system\u003c\/li\u003e\n  \u003cli\u003eWear plate (911703) — provides sealing surface for the impeller\u003c\/li\u003e\n  \u003cli\u003eGasket (911702) and Seal (911704) — prevent leaks at mating surfaces\u003c\/li\u003e\n  \u003cli\u003eImpeller liner\/cup (764197) and Housing (984744) — restore proper chamber fit and performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow difficult is installation and what should I prepare?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable with basic marine maintenance and using hand tools. Typical steps include removing the drive unit, draining cooling passages, disassembling the pump, replacing all kit parts, and reassembling with correct torque and sealant where recommended. If you’re unsure, a marine mechanic can complete the job in a short service visit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTools needed: basic socket set, screwdrivers, pliers and a gasket scraper\u003c\/li\u003e\n  \u003cli\u003eTime: expect 1–3 hours depending on experience and access\u003c\/li\u003e\n  \u003cli\u003eTip: inspect raw-water pickup and hoses while pump is out\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this kit prevent future cooling issues?\u003c\/h3\u003e\n\u003cp\u003eUsing fresh components from this kit restores the pump’s internal clearances and sealing, which often corrects flow loss caused by worn parts. While new parts greatly reduce risk from pump wear, they don’t prevent unrelated issues like clogged strainers, blocked through-hulls or damaged raw-water lines; inspect the whole cooling system for best results.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAddresses common wear points inside the pump housing\u003c\/li\u003e\n  \u003cli\u003eImproves sealing and impeller engagement to recover flow\u003c\/li\u003e\n  \u003cli\u003eCombine with system inspection to minimize repeat problems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The GHmarine 984461 kit is aimed at boat owners, DIY marine technicians, and professional mechanics who service OMC Cobra stern drives from 1986–1993 (except specified exclusions).
