Sierra

Sierra Marine Impellers are replacement components for compatible marine water pumps and raw-water cooling systems, helping maintain proper water circulation through outboard, sterndrive, inboard, and other marine applications. Sierra offers impellers in a wide range of sizes and configurations to fit specific engine and pump applications. A flexible marine impeller is a wear item that should be inspected regularly and replaced according to the engine or pump manufacturer's maintenance recommendations. Operating a pump without adequate water supply can damage a flexible impeller, making proper installation and maintenance especially important.

Find the Correct Sierra Impeller

Marine impellers are not one-size-fits-all.

Selecting the correct replacement impeller helps ensure proper fitment and supports dependable water circulation within the marine cooling system.
