Mercury 47-59362T1 Sea Water Pump Impeller

Mercury 47-59362T1 Sea Water Pump Impeller

Maintain dependable cooling system performance with the Mercury 47-59362T1 Sea Water Pump Impeller. Designed as a genuine OEM replacement, this impeller helps restore proper raw water circulation through the engine and exhaust system to protect against overheating and cooling system failure.

The raw water pump impeller is one of the most important maintenance items in any marine engine. As the flexible rubber vanes age, they can become brittle, crack, or lose efficiency from heat, debris, and continuous operation. Replacing the impeller at recommended service intervals helps maintain strong water flow and reliable engine cooling during demanding conditions on the water.

Manufactured to Mercury Marine factory specifications, the 47-59362T1 impeller is built using durable marine-grade rubber compounds designed for long service life in both freshwater and saltwater applications. Designed as a direct replacement for compatible sea water pump systems, it provides reliable fitment and straightforward installation.
