Performance & Practical Benefits

A good starter is about trust — knowing your engine will respond instantly, no matter how many times you’ve launched, trolled, or docked that day. The 808011A05 provides the torque and reliability required for marine ignition systems, engaging cleanly and cranking strong every time.

The 9-tooth pinion gear ensures solid contact with the flywheel for smooth, slip-free starts. The rear-entry design offers clean installation and easy service access, while its OEM construction means it fits perfectly the first time. Inside, marine-specific sealing helps keep out moisture and corrosion — a must for boats that live in damp bilges or see regular splashes of salt spray.

From weekend cruisers to working inboards, this starter delivers the confidence that comes only from Mercury-engineered components built to handle real-world boating conditions.

Why Buy OEM

With something as vital as a starter, guessing isn’t an option. OEM starters from Mercury Marine are tested for amperage draw, torque output, and engagement reliability under marine-specific heat and vibration. Cheaper aftermarket units might look similar, but they rarely match Mercury’s internal design tolerances or corrosion resistance.

Choosing OEM means you’re investing in longevity — a starter that cranks strong season after season, fits without fuss, and performs the way Mercury intended. It’s about doing the job once and doing it right.
