Product Description
The 6Y1-24360-52 Primer Pump Assy is designed for Yamaha outboard motor fuel systems using a 6mm fuel line.
The primer bulb is an important part of the outboard fuel supply system. Before starting the engine, squeezing the primer bulb helps draw fuel from the fuel tank through the fuel hose and toward the engine, helping the fuel system become properly primed.
A worn, hardened, cracked or leaking primer bulb may cause difficult starting, poor fuel delivery or air entering the fuel line. Replacing an aging primer pump can help maintain reliable fuel flow and normal engine starting performance.
Key Features
- Replacement for Yamaha part number 6Y1-24360-52
- Designed for 6mm fuel hose systems
- Flexible and durable primer bulb construction
- Helps provide reliable fuel priming

Function
The primer pump is installed in the fuel line between the fuel tank and the outboard motor.
By manually squeezing the bulb, fuel is drawn through the fuel hose and pushed toward the engine. This helps remove air from the fuel line and prepares the fuel system before engine starting.
When Should the Primer Bulb Be Replaced?
We recommend checking or replacing the primer pump if you notice:
- Primer bulb becomes hard or brittle
- Cracks appear on the rubber surface
- Fuel leakage around the bulb or hose connection
- Primer bulb does not return to its original shape
- Bulb cannot become firm after repeated squeezing
- Engine becomes difficult to start
- Air repeatedly enters the fuel line
- Unstable fuel supply during operation
