Quicksilver Water Pump Impeller for MerCruiser Engines — 59362T1, Plastic Housing Direct-Fit, Durable Elastomer Vanes

This impeller restores proper raw-water circulation for cooling systems on compatible MerCruiser marine engines. Made by Quicksilver — a long-standing OEM supplier for Mercury Marine — this part is engineered to meet factory specifications for fit, durability, and flow. It replaces worn or damaged impellers to help maintain engine temperature control and prevent overheating caused by reduced water flow.

How does this impeller improve engine cooling performance?

The 59362T1 uses elastomer vanes with enhanced flexibility that retain shape across a wide range of temperatures, maintaining consistent water flow. A bonded center insert secures the vanes to the hub, reducing the chance of vane tear-out under load. Together these features sustain higher flow rates compared with degraded or generic impellers.

• Elastomer vanes designed for flexibility in varied water and ambient temperatures
• Bonded center insert prevents vane separation and sudden flow loss
• Engineered to provide stable, higher raw-water flow for cooling circuits

Will this impeller fit my MerCruiser with a plastic pump housing?

The 59362T1 is specified for MerCruiser engines that use engine-mounted sea water pumps with plastic housings. Confirm compatibility by matching the OEM part number or comparing the physical dimensions and vane layout to your existing impeller. If needed, consult your engine’s parts diagram or a dealer to verify fitment before installation.

• Designed as a direct replacement for MerCruiser models with plastic pump housings
• Match OEM part number 59362T1 or compare dimensions for confirmation
• Dealer or engine parts diagram can verify compatibility quickly

How long does a Quicksilver impeller last and when should I replace it?

Service life depends on use, water conditions, and storage, but routine seasonal inspection is recommended. Replace the impeller if vanes show cracking, brittleness, missing pieces, or if water flow has declined. Many owners replace the impeller as part of annual maintenance or pre-season commissioning to avoid failures on the water.

• Inspect for cracks, brittle vanes, or missing sections each season
• Replace at first signs of wear or annually for preventive care
• Replace immediately if cooling flow drops or engine overheats

What are the practical benefits of choosing the Quicksilver brand?

Quicksilver is a manufacturer and OEM supplier with extensive testing and development in marine environments. Choosing the branded impeller gives confidence in fit and material quality, plus access to parts supported by Mercury Marine specifications. This reduces the risk of premature failure compared with untested aftermarket substitutes.

• OEM-level quality and specification alignment with Mercury Marine
• Materials tested for marine stressors and temperature variation
• Backed by a long-standing supplier reputation in the marine industry

Who is this for: The Quicksilver 59362T1 impeller is intended for MerCruiser boat owners, technicians, and fleet managers who need a reliable, OEM-grade replacement for engine-mounted sea water pumps with plastic housings. It's suitable for preventive seasonal maintenance or emergency replacement when vane damage or reduced water flow threatens engine cooling performance.
