The raw water engine pump is the core of the marine engine, providing a consistent flow of cooling water to maintain temperatures that are in accordance with the engine's demanding performance. Johnson Pumps have achieved a reputation for excellence in quality over the years and are now preferred by the most prestigious marine engine manufacturers in Europe. Johnson Pumps are installed on some of the most well-known engine brands in both commercial and pleasure boats. To guarantee that your boat engine cooling pump functions as intended, it is recommended that you conduct regular preventative maintenance and inspections. The Johnson water pump impeller should be replaced every 3 to 12 months, depending on the application. The most common cause of premature engine failure is the failure of the raw water pump.
