SKU:S5M183073
The Sierra Marine 183073 Impeller is a replacement service component for compatible marine cooling systems. It is designed to help maintain the circulation of water through the engine cooling circuit, supporting proper heat transfer during normal operation. Replacing a worn or damaged impeller can help restore dependable cooling performance and reduce the risk of insufficient water flow caused by deteriorated pump components.
Use the Sierra Marine 183073 as part of a scheduled marine engine maintenance program or when inspection reveals signs of wear, cracking, deformation, missing vanes, or reduced pumping performance. Regular impeller inspection is especially important for boats that experience frequent use, extended storage, or operation in conditions where debris may enter the water supply. A serviceable impeller helps the cooling system operate as intended and supports reliable engine performance on the water.
Before installation, confirm that the part number matches the requirements of your engine, water pump, and application. Inspect the pump housing, cover, key, gasket, and related components for wear or damage, and replace any parts that could affect sealing or impeller operation. Follow the engine manufacturer’s service procedures for removal, lubrication, installation, and break-in. The Sierra Marine 183073 provides a practical replacement option for marine maintenance professionals, boat owners, and service technicians seeking a correctly identified impeller for a compatible application.
