🔌 Function

The water pump draws cooling water through the gearcase intake and circulates it through the engine cooling passages. Renewing the housing, liner, wear plate, impeller and seals restores the pump chamber clearances needed for reliable cooling-water pressure.

Common signs replacement is required:

• Weak, intermittent or absent tell-tale stream

• Engine overheat alarm or rising cylinder-head temperature

• Steam, reduced cooling-water discharge or salt blockage symptoms

• Missing, cracked, hardened or permanently bent impeller vanes

• Scored, corroded or distorted pump housing, liner or wear plate

📦 Condition

• Brand-new aftermarket replacement kit

• Supplied as new replacement components

• Supplied in suitable retail or equivalent packaging
