The 8M6007332 delivers fast, confident starting thanks to its permanent magnet design, which produces strong torque without hesitation. You’ll feel the difference on cool mornings when the engine needs a little more encouragement, or after a long day of cycling between spots.

Why Buy OEM

With something as essential as a starter, cutting corners just isn’t worth it. A genuine Quicksilver starter is engineered specifically for the electrical and mechanical characteristics of Mercury outboards—no guesswork, no compromises. Aftermarket options may fit, but they rarely match the longevity, torque consistency, or safety certification that Mercury requires.

Choosing OEM means your engine gets the correct internal tolerances, the right rotation direction, and materials tested in the same harsh environments your boat sees every season. It’s the practical choice for boaters who want reliability, not surprises.
