Performance & Practical Benefits

The 819503T6 delivers steady voltage from your battery straight to your starter motor, making your engine crank faster and start smoother. The sealed housing keeps corrosion and moisture out, even in saltwater, while the strong internal contacts handle high current without sticking or pitting.

It installs quickly with basic tools — no rewiring or modifications needed. Once in, you’ll notice a big difference in reliability: no more weak clicks or slow cranks, just a confident start every time.

Why Buy OEM

Mercury’s OEM solenoids are designed for real-world boating, built with better insulation, stronger springs, and corrosion-proof casings. Aftermarket copies might work for a while but often fail early or fit poorly.

A genuine Quicksilver solenoid gives you the same quality, fit, and durability Mercury designed into your engine from the start. It’s one of those small upgrades that keeps your boat dependable for the long haul.
