Mercury – Quicksilver Rotor Assembly | Ignition System Component | Coated Brass and Polymer | 13524T12

Overview

When you run a tow sport boat, your engine doesn’t get much of a break. It idles long, jumps hard, and spends its life bouncing between full throttle and steady pulls. The Mercury Marine 13524T12 Quicksilver Rotor Assembly is built for that kind of work. Designed for MerCruiser Black Scorpion engines, it keeps your ignition firing smooth and steady, no matter how hard the load. It’s the part that makes the difference between a sluggish pull and the kind of clean, instant response that feels just right behind the wheel.

Key Features

• Purpose: Distributes spark timing accurately for reliable ignition on Black Scorpion engines.
• Construction: Molded from durable polymer with a coated brass contact blade for strong conductivity.
• Performance: Delivers consistent spark and timing through the entire RPM range.
• Fitment: Built for MerCruiser Black Scorpion Tow Sport outboards (serial numbers 0M391600–2A460164) and MX 6.2L Black Scorpion models (serial numbers 0M391750–2A460138).
• Durability: Resists corrosion, heat, and vibration in high-demand marine environments.
• Included: Rotor assembly only — ready for direct installation.
• OEM Quality: Manufactured to Mercury Marine original standards for accuracy and dependability.

Engine & Boat Compatibility

• MerCruiser Black Scorpion Tow Sport and MX 6.2L Black Scorpion engines within the listed serial number ranges.
• Common on wakeboard, ski, and tow boats that rely on smooth throttle response and strong pulling power.
• Compatible with V8 marine engines designed for torque-heavy applications.
• Performs equally well in freshwater or saltwater conditions.

Performance & Practical Benefits

This rotor keeps the heart of your ignition system in sync. The brass contact ensures a clean, strong spark, while the polymer body stays solid even after hours of high-heat operation. Every rotation is precise, giving you the quick starts and responsive pull you expect from a Black Scorpion engine.

It’s built for the realities of boating — humidity, vibration, and long idle times between bursts of throttle. You’ll feel the difference right away: cleaner ignition, steady idle, and stronger response when you push the lever forward. It’s the kind of reliability that lets you focus on the ride, not the equipment.

Why Buy OEM

You can spot the difference between genuine Mercury parts and generic ones the moment you install them. The Quicksilver 13524T12 is made for your exact ignition system — balanced, tuned, and tested by the same engineers who built the motor. Aftermarket versions might look similar, but their materials and tolerances can’t match Mercury’s precision.

This rotor was built for long days on the water and the stress of real towing conditions. It won’t crack, corrode, or throw off timing when the heat builds. With Mercury OEM parts, you’re not guessing — you’re using gear that’s proven to perform.
