With an engine as powerful as the 8.2L, you can feel instantly when the ignition system is healthy — the smooth startup, the steady idle, the way the boat responds the moment you bring the throttle forward. The Quicksilver 899329A09 Spark Plug Wire Kit keeps that confidence alive. It’s built for engines that work hard, whether you’re loaded down for a weekend run, cruising a long stretch of lake, or pulling your crew on a wakeboard. Good spark means good power, and this kit keeps it flowing clean.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eKey Features\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eComplete set of \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e8 red spark plug wires\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePre-formed boots for precise fit at the plug end\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eTailored wire lengths ensure correct routing on 8.2L MerCruiser engines\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngineered for durability in high-heat marine engine compartments\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eDesigned for long-term ignition efficiency and consistent spark delivery\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEngine \u0026amp; Boat Compatibility\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eFits \u003c\/span\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003e8.2L MerCruiser sterndrive and inboard engines (2010 and newer)\u003c\/span\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan data-preserver-spaces=\"true\"\u003eWorks with:\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBravo sterndrive-powered sport boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eLarge bowriders and deck boats\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance cruisers\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCabin cruisers and weekenders\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan data-preserver-spaces=\"true\"\u003eCompatible with ignition systems requiring OEM spark plug wire sets\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan data-preserver-spaces=\"true\"\u003ePerformance \u0026amp; Practical Benefits\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003e Ignition wires seem simple, but in a marine engine bay they’re under constant stress — heat buildup, vibration, moisture, and tight routing all take a toll. Over time, wires can break down internally or begin leaking voltage, which leads to misfires, sluggish acceleration, and reduced fuel efficiency. The Quicksilver 899329A09 kit solves those problems with wires engineered specifically for your 8.2L engine’s layout.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eEach wire is cut to the exact length Mercury designed for the engine. This matters more than most boaters realize — correct length reduces stress at connection points, prevents rubbing or chafing, and ensures each wire reaches the plug cleanly without looping or stretching. The boots grip firmly, holding their seal even through the vibration of rough water or long, high-RPM runs.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eInside each wire, high-quality insulation and core materials help maintain a strong, stable spark across all eight cylinders. That translates directly into smoother idle, stronger hole shot, and more reliable performance under load. When towing, cruising, or maneuvering at the dock, the engine feels responsive and balanced — exactly how a big-block MerCruiser should feel.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-preserver-spaces=\"true\"\u003eBecause these wires are made for the marine environment, they resist moisture intrusion, thermal cracking, and corrosion far better than automotive-style wires.

That can lead to premature wear, poor spark quality, or misfires that mimic larger engine problems. OEM Quicksilver wires are engineered for the exact heat load, routing angles, and performance expectations of the 8.2L MerCruiser.
