When you turn the key and hear that clean, confident crank, everything else falls into place—the fishing rods feel lighter, the breeze feels better, and the shoreline slowly slips behind you. This Mercury Marine part brings that reliable start to engines that work hard in real-world conditions. Whether it’s a nimble thirty horsepower two-stroke or a three-cylinder jet setup pushing upriver, this starter gives you the steady spark of confidence boaters depend on.

Performance & Practical Benefits
This starter motor is built for engines that see real work—from shallow river runs to long days drifting bait lines. You’ll feel the difference the moment you turn the key. The crank feels tight and secure, without hesitation or stumble. It’s the kind of steady engagement that makes the engine come alive quickly, even after long idle periods or damp early-morning starts.

Inside, the armature and brushes are engineered specifically for two-stroke and jet applications, where compression and load differ from four-stroke engines. The marine-grade steel housing stands up to vibration, heat, and moisture, giving you a starter that stays dependable season after season. Once installed, it seats cleanly without forcing or adjusting, making the whole process feel natural and stress-free.

Why Buy OEM
Two-stroke and jet engines demand a precise starter motor. Aftermarket units often struggle to match Mercury’s torque values or internal tolerances, leading to weak starts or premature wear. A genuine Mercury Marine part eliminates those problems entirely. It fits the way it should, performs the way the engine expects, and protects your electrical system from unnecessary strain.

If you’ve ever been miles upriver or offshore hoping your engine fires without hesitation, you already know why OEM matters.
