Installation Notes

Installation should be performed by a qualified marine mechanic. The process generally involves disconnecting the lower unit, removing the old water pump assembly and housing, cleaning the mounting surfaces, and installing the new housing with a new impeller and gaskets. Ensure all bolts are torqued to the manufacturer's specified values and verify proper cooling system operation after reassembly.

Troubleshooting & FAQ

Which Yamaha engines does this housing fit?

This housing is compatible with Yamaha 4-stroke models F75, F80, F90, and F100 (2006–present) and 2-stroke model C85 (1989–1991, 1996–1997). It also cross-references to the jet drive variants of the same 4-stroke models.

What is the purpose of the weep hole?

The small weep hole is a diagnostic feature. If you see water or coolant dripping from it, it indicates that an internal seal has failed. This allows you to address the issue before more significant damage occurs to the powerhead or lower unit.

What are the signs of a failing water pump housing?

Signs of failure include engine overheating alarms, a weak or non-existent stream of water from the tell-tale outlet, visible cracks or corrosion on the housing, or signs of melting on the plastic components of the water pump assembly.

How often should the water pump assembly be serviced?

As a general rule, the entire water pump assembly, including the impeller and gaskets, should be inspected annually and replaced every 2-3 years or 200-300 hours of use, whichever comes first. The housing should be replaced if it shows any signs of wear, corrosion, or heat damage.
