SIERRA 18-36001 Raw Water Pump

Compatible Engines

The original SIERRA 18-36001 raw water pump is a critical component of the cooling system, engineered for reliability in harsh marine conditions. This OEM-class component ensures precise fitment and long service life. Due to the specific applications in industry and boating, compatibility with specific engine models (e.g., Mercury, Volvo Penta) requires verification. We recommend checking the catalog number 18-36001 or the original OE number in your unit's manual. If you have any doubts about selecting the right part for your engine, please contact our customer support team to confirm fitment.

Installation and Operation

Replacing the pump is a task that can be performed independently with care. Before disassembly, ensure the engine is off and the system is depressurized. It is crucial to check the condition of the seals and the exhaust flange, as leaks in this area can lead to air ingestion and pump failure. After installing the new SIERRA pump, we recommend filling the system with fresh water before the first startup to avoid dry running. Regular maintenance of the cooling system extends the life of not only the pump but the entire engine.
