Why Buy OEM

Mercury’s OEM solenoids are engineered specifically for marine duty — sealed, corrosion-resistant, and built to last. Aftermarket versions often use cheaper materials and weaker internal parts that fail early in harsh conditions.

A genuine Quicksilver solenoid guarantees the right fit, proper current handling, and the long-term reliability Mercury engines are known for.
