Performance & Practical Benefits
Out on the water, this starter feels tight and sure every time you ask it to work. When you push the button or twist the key, you get a quick, confident spin instead of a slow, uncertain grind. The permanent magnet direct drive layout gives you smooth, steady torque that turns the engine over without sounding strained or harsh.

In daily use, that performance shows up in small but important ways. Cold morning? It still cranks with authority. Long idle at the sandbar? It lights back up without complaint when you are ready to head home. The protected armature and carefully chosen internal bearings help the unit shrug off heat, vibration, and moisture, which are all part of real marine life. Installation is straightforward if you follow the service information, and once it is bolted in, it quickly becomes one of those parts you forget about because it just keeps doing its job.

Why Buy OEM
When you are trusting a single outboard to get you and your crew home, saving a few dollars on a starter rarely feels like a win. A genuine Mercury Marine original equipment manufacturer starter is built around the specific rotation, gear mesh, and electrical demands of your Nissan or Suzuki outboard. That means cleaner engagement, less wear on your flywheel, and fewer mysterious starting issues down the road.

Over time, that accuracy pays for itself. You spend less time chasing electrical gremlins, and more time actually using the boat. If a friend at the dock asked what to run for a replacement starter on a compatible Nissan or Suzuki outboard, this is the part number I would suggest—because it is designed to fit right, work right, and keep working.
