Performance & Practical Benefits

You’ll notice the difference the first time you turn the key. This starter delivers a crisp, confident crank that engages without hesitation — something especially important for mid-size Suzuki outboards that work hard across long days on the water. The permanent magnet design helps maintain strong torque even in cooler mornings or after long periods of downtime.

Its durability is equally impressive. The internal components are insulated, secure, and designed to handle the vibration, moisture, and heat that come with real marine use. The high-temperature epoxy armatures help protect wiring from corrosion, while the bearings maintain a smooth, steady spin under load. You can trust this starter to perform whether you’re running in choppy coastal conditions or spending the day on a quiet lake.

Installation is simple thanks to its OEM-aligned design, giving you a clean, accurate fit that doesn’t require modification or guessing. Once installed, the starter becomes a dependable part of your engine’s rhythm — the beginning of every good day on the water.

Why Buy OEM

Choosing a genuine Mercury Marine part means choosing dependability over uncertainty. Aftermarket starters often look similar, but their internal tolerances, torque output, and material quality rarely match OEM requirements. The 8M6007390 is engineered to meet strict performance standards, so you get clean engagement, long service life, and fewer mechanical surprises. It’s the kind of part that protects your investment and saves you headaches down the line — the sort of wisdom experienced boaters pass on because they’ve seen what happens when shortcuts are taken.
