Tip: Always confirm compatibility with your Yamaha outboard serial number before ordering.

Why Replace Your Yamaha Water Pump?

Your outboard’s water pump is the heart of its cooling system. Over time, the impeller and related components wear down, leading to reduced water flow and risk of overheating. Replacing the water pump at regular intervals ensures:

• Reliable cooling performance
• Protection against costly engine overheating
• Extended outboard lifespan

Yamaha recommends inspecting/replacing your water pump every 2–3 seasons or every 300 hours, depending on usage.

Installation & Maintenance

Installing the Yamaha 61A-W0078-A4-00 kit typically requires:

• Removing the lower unit
• Disassembling the old water pump housing
• Installing the new impeller, O-rings, and gaskets
• Reassembling and torquing bolts to spec

Note: Installation complexity varies by model. We recommend using a Yamaha service manual or professional technician for best results.
