SUZUKI WATER PUMP KIT 17400-92D01

Function and technical context

This water pump kit is part of the outboard engine's water cooling system, being the component responsible for driving the flow of seawater through the entire cooling circuit. The set includes the necessary elements to restore the correct operation of the pump: impeller, gaskets, seals and other wear parts that guarantee efficient pumping. A deteriorated impeller or gaskets in poor condition cause insufficient cooling which can lead to engine overheating, loss of power and, in severe cases, irreversible damage to the cylinder head or pistons. Keeping this assembly in perfect condition is essential for the reliability and longevity of the engine on any day of navigation.

When to replace this part?

The most common symptom of a water pump kit in poor condition is the absence or reduction of the cooling water jet (nozzle) on the engine bulkhead, frequently accompanied by an unusual temperature increase or the safety thermostat tripping. It is recommended to replace the impeller and seals of the water pump every 200-300 hours of operation or at the beginning of each season, since the rubber of the impeller hardens and loses flexibility over time even if it does not show external signs of breakage. Renewing this set preventively before each season avoids water breakdowns and the costly emergency interventions that entail.
