Performance & Real-World Benefits

The 805759T05 distributor cap kit ensures your ignition system delivers consistent, powerful spark under all conditions. Over time, moisture and heat can break down the cap and rotor, causing weak spark, misfires, or hesitation. This OEM kit brings back that strong, even spark your Black Scorpion engine depends on for crisp throttle response and steady towing power.

With its rugged construction and brass terminals, it stands up to marine punishment — constant vibration, salt exposure, and high operating temperatures. The included gasket keeps moisture out, preventing corrosion and electrical arcing. Whether you’re idling at the dock or pulling a wakeboarder, this cap kit keeps your ignition solid and your engine ready to go.

Why Choose Mercury OEM

The Quicksilver 805759T05 is a genuine Mercury Marine part, made to the same standards as the components installed at the factory. Aftermarket versions might fit, but they rarely match the heat tolerance, sealing quality, or electrical precision of OEM parts.

Mercury’s OEM cap kits are tested in real marine environments — long runs, rough water, and high humidity — ensuring they perform when it matters most. It’s the same part trusted by Mercury technicians and performance boat builders who know reliability starts with genuine parts.
