FREPURDO Water Pump Impeller Repair Kit for Yamaha 60–90HP – Complete Rebuild with Housing & Gaskets, OEM Replacement

FREPURDO's complete water pump impeller repair kit replaces Yamaha OEM 692-W0078-02-00 to restore cooling on 60–90HP 2-stroke outboards.

If your Yamaha 60, 70, 75, 80, 85 or 90 HP 2-stroke outboard is showing signs of reduced cooling or has been serviced many seasons ago, this all-in-one repair kit provides the parts needed to rebuild the raw water pump to factory-style performance. The kit bundles the impeller with its housing, wearplate, gaskets, seals and hardware so you can swap the critical components in a single service session without hunting for separate pieces.

How does this kit restore my outboard's cooling system?

Replacing the impeller and related components reestablishes consistent water flow through the engine's cooling passages. Worn vanes or a damaged housing reduce pump efficiency and raise engine temperatures; installing fresh parts returns intended flow rates and sealing surfaces.

• Includes impeller, wear plate and insert cup to renew pump internals.
• New housing for correct internal clearances and improved sealing.
• Gaskets and O-ring to prevent leaks at mating surfaces.
• Mounting bolts and woodruff key for secure, correct timing of the impeller.

Which Yamaha engines and years fit this replacement kit?

This repair kit is engineered to match the dimensions and mounting pattern of the Yamaha OEM 692-W0078-02-00 assembly, covering a broad set of 60–90HP 2-stroke models. It's intended for specific TLR designations and other compatible 60–90HP engines, so it aligns with both parts and service procedures for those units.

• Fits 60TLR models (2004–2005) and 70TLR (2004–2009).
• Compatible with 90TLR (2002–2005), C90TLR (1997–2001), and B90TLR (1997–1999).
• Also suitable for C75, C80, and P75 designs where OEM part number applies.
• Engineers the same critical clearances as the referenced Yamaha OEM part.

What parts are included and what should I inspect during installation?

The kit ships as a full pump rebuild package so you replace all wear-prone components at once. While installing, inspect the pump shaft, keyway and cooling passages for scoring, corrosion or debris that could compromise the new parts.

• Full set: water pump housing, impeller, wear plate, insert cup, gaskets, O-ring.
• Hardware: woodruff key and mounting bolts for correct alignment and torque.
• Check shaft for grooves and ensure the key seats properly in the impeller hub.
• Clear intake screens and passages to avoid premature impeller damage.

How long will the repair last and how often should I service the impeller?

Service intervals vary with use, storage practices and water conditions; routine inspection is the safest approach. Many owners replace impellers every season or every 100 hours for heavy use, but visual checks after winter layup or extended idle periods help catch early deterioration.

• Typical preventive replacement: annually or per manufacturer-hour recommendation.
• Inspect vanes for cracking, collapse or missing sections before each season.
• Replace immediately if impeller shows distortion or if cooling performance drops.
• Use antifreeze or corrosion inhibitor during winterization to preserve rubber components.

Who is this for: Boaters, marine mechanics and fleet maintenance teams who own or service Yamaha 60–90HP 2-stroke outboards and want a single SKU that contains all necessary components to rebuild the water pump to OEM-equivalent specifications. If you need an OEM 692-W0078-02-00 replacement with housing, seals and hardware in one package, this FREPURDO kit simplifies the job and reduces parts-sourcing time.
