YAMAHA MEMBRANE 6E5-24471-00

Function and technical context

The 6E5-24471-00 membrane is a critical component of the fuel system on Yamaha outboard engines. This piece acts as a watertight separator within the petrol pump, allowing the controlled circulation of fuel to the injectors while preventing the passage of vapor and contaminants. The membrane works under variable pressure, adapting to changes in engine demand during acceleration, idle and cruising. Its integrity is essential to maintain fuel pressure within specified ranges; Any deterioration causes loss of pressure, poor fuel atomization and difficult starts or loss of power during navigation.

When to replace this part?

Symptoms of diaphragm wear include intermittent failures when starting, progressive loss of power, irregular engine operation and, in advanced cases, complete stoppage while sailing. The membranes are affected by exposure to low quality fuel, water in the tank and continuous engine vibrations; It is recommended to inspect its condition every navigation season and replace it preventively every two or three years of regular use. Replacing this part preventatively prevents being left in the water and costly emergency repairs far from port.
