Quicksilver Solenoids

Quicksilver Solenoids: OEM-Grade Reliability for Marine Engines

When your outboard or sterndrive hesitates at the key, a failing solenoid is often the culprit. Quicksilver solenoids are engineered specifically to restore that instant, dependable ignition your marine engine demands — backed by the same original-equipment expertise that powers Mercury Marine engines from the factory.

Solenoids are electromagnetic switches that serve as the critical link between your battery and your starter motor (or power trim system). When current flows through the solenoid coil, it closes a high-amperage circuit, delivering the surge of power needed to crank the engine or actuate the trim. Because they're exposed to saltwater spray, constant vibration, heat, and moisture, marine solenoids face conditions far harsher than their automotive counterparts — and that's precisely where Quicksilver's pedigree makes a difference.

Why Choose Quicksilver Solenoids?

Manufactured by an OEM, not an aftermarket supplier. Quicksilver holds a unique position in the marine parts market: it is the only marine aftermarket brand manufactured and recommended by an original equipment manufacturer. Every solenoid is produced to match Mercury Marine’s stringent OEM performance specifications, ensuring a fit and function identical to what came on the engine originally.

• Starter Solenoids – Flat-mount and remote-mount designs for a wide range of Mercury and Mariner outboards and MerCruiser sterndrives (e.g., part 8M0185149), delivering full voltage to the starter motor on every crank.
• Power Trim & Tilt Solenoids – Dual-solenoid setups (e.g., part 8M0185622) used on MerCruiser stern drives with plastic-reservoir trim pumps, controlling up and down trim movement reliably under load.
• Solenoid Kits – Complete replacement kits such as the 819503A5 (Mercury TwoStroke and Jet outboards, 30–60 HP) and the 853654A1 (Mercury 2-cylinder outboards and MerCruiser inline-6 engines) that include mounting hardware for a clean, straightforward installation.

Quicksilver solenoids are sealed and corrosion-resistant, designed to withstand the daily realities of saltwater, heat, and constant movement that outboards and sterndrives experience. Generic aftermarket solenoids may appear similar on paper, but they typically lack the pressure-testing and material validation that Quicksilver applies to every component it produces.

Broad Fitment Coverage

One of the strongest arguments for choosing Quicksilver solenoids is coverage. The lineup spans 2-stroke and 4-stroke Mercury and Mariner outboards from 9.9 HP all the way through high-displacement V-series motors, as well as MerCruiser inboard and sterndrive applications. Quicksilver also produces parts compatible with other leading marine engine brands including Honda, Yamaha, Evinrude/Johnson, and Suzuki — making it a practical single-source solution for multi-brand fleets or marina service shops.

Whether you are performing a routine maintenance refresh or tracking down an intermittent no-start condition, Quicksilver solenoids give you the confidence of OEM-level engineering without the dealership-only distribution constraint.
