Parts Desk Insight – Best Use
The 6-7779003 is a complete pulley-driven pump unit — not a service kit or bare impeller. At $992 and 2,812g this is a full pump assembly intended for OEM-style installation or direct replacement of a failed unit. The pulley-drive configuration is common on older inboard engine installations where the pump is belt-driven off the engine rather than flange-mounted. Key service advantages: the replaceable cam and wearplate design means the pump housing can be rebuilt rather than replaced when internal wear occurs — stock the 836 series impeller and service kit alongside this unit to support post-sale service calls. Nitrile impeller is correct for raw water circuits with potential petroleum exposure; if the installation is a clean raw water circuit, a neoprene impeller swap at first service is acceptable. Bidirectional rotation simplifies installation — confirm port orientation required before ordering as multiple configurations exist in the 7779 series.
