Mercury – Champion L76V Spark Plug | Ignition Component | Copper Core & Ceramic | Part Number 896329827

Overview

There’s a certain comfort in knowing your engine will light off cleanly every time you turn the key. The Champion L76V Spark Plug brings that confidence back to Force TwoStroke outboards and SportJet engines — the kind of steady, predictable spark that makes mornings on the water feel effortless. It’s a simple part, yet it shapes every moment you spend on the boat. From the calm rumble as you drift away from the dock to the responsive pull when you throttle up, this plug helps your engine feel alive, clean, and eager for the day ahead.

Performance & Practical Benefits

The difference between a tired spark plug and a healthy one is something you can feel. With the L76V installed, your engine fires faster and idles smoother — the kind of steady rhythm that makes small waterways and tight marinas feel easier to navigate. On the throttle, the plug delivers a clean, consistent spark that helps the engine climb through its rpm range with fewer stumbles or hesitation.

The copper core electrode is built to handle the demands of TwoStroke combustion, dissipating heat quickly and maintaining the right temperature for a strong, repeatable spark. That stability makes your engine less prone to fouling, especially during long idle periods or slow trolling runs. And because this plug reduces radio interference, your onboard electronics — from fish finders to communication gear — stay clearer and more reliable.

You’ll notice the difference on long days too. The engine feels more predictable, the throttle response stays sharp, and the entire running attitude of the boat becomes more relaxed. It’s a small part that quietly improves the whole experience.

Why Buy OEM

Ignition components aren’t the place to experiment. Mercury Marine chooses specific plugs for very specific reasons — heat range, firing characteristics, electrode design, and the way the plug behaves inside a marine combustion chamber. Aftermarket substitutes may look similar, but even slight differences can cause rough running, premature wear, or fuel inefficiency. This OEM-specified Champion plug gives you the exact performance Mercury intended. It’s a practical, reliable choice that seasoned boaters trust because it simply works.
