Why Buy OEM

A genuine Mercury Marine part like the 853654A1 Solenoid Kit isn’t just a replacement — it’s the same engineering that came with your engine from the factory. Mercury’s solenoids are tested through extreme heat, vibration, and corrosion simulations to ensure they meet the company’s demanding marine standards. Aftermarket options might look similar, but their internals often lack the precision and material quality needed for long-term marine use.

With OEM, you know the fit is perfect, the function is reliable, and the lifespan is proven. It’s a smart choice for boaters who care about long-term performance and want their ignition systems to work right the first time, every time.

When your day depends on your engine starting smoothly, cutting corners just isn’t worth it — and with Mercury OEM, you’ll never have to.
