Service recommendation

Raw water pump impellers are wear items and should be inspected regularly and replaced at the intervals recommended by the engine manufacturer, or sooner if there are signs of cracking, stiffness or missing blades. Keeping a spare 500122T impeller onboard helps avoid overheating and unplanned downtime during the season.
