MerCruiser Bravo 4.3 / 5.0 / 5.7 (350) Raw Water Pump with Impeller and Pulley - 46-807151A9

Product Overview

This raw water pump with impeller and pulley is a replacement for MerCruiser Bravo sterndrive engines in 4.3L, 5.0L and 5.7L (350) form, referencing OEM part number 46-807151A9. The belt-driven pump supplies cooling water from the lake or sea to the engine, so its condition is critical to preventing overheating. Fitting a fresh pump assembly is a sensible step during routine maintenance or after an overheat event, and having a spare on hand can save a ruined day on the water.

After installation, confirm strong water flow from the exhaust outlets and inspect for leaks. A qualified marine technician is recommended for this job.
