About this part
This page covers the genuine Yamaha part 6H5819501000 (Relay Assembly). It’s an original OEM component designed to match Yamaha’s factory tolerances for correct fit, reliable function, and long service life in marine conditions.
Why choose genuine Yamaha?
OEM parts are produced to the same specification as the original component fitted at the factory. That means correct materials, correct dimensions and consistent fit — especially important on units where corrosion, heat cycles, and vibration are normal.
Notes for this part
Installation tip: clean terminals, check cable condition, and ensure mounting/earthing points are corrosion-free. Excessive voltage drop from tired cables can mimic relay faults.
Relays/solenoids switch high current circuits like starting. Symptoms of a failing unit can include intermittent cranking, a click with no crank, or heat-related starting issues that come and go.
Warranty
New genuine parts include a 1-year warranty (correct application and installation required).
Ordering tips
Ordering tip: when buying multiple items, it’s worth reviewing the same diagram section for related gaskets and seals so everything arrives together.
