Performance & Practical Benefits

You’ll feel the difference the first time you shift after installing this actuator. The movement is crisp, controlled, and steady, giving you a direct connection between the throttle and the engine. There’s no hesitation, no loose or wandering sensation — just smooth, confident transitions as the gears settle into place. That kind of precision matters when you’re docking in a tight slip or working through a crowded inlet on a windy afternoon.

Its hardcoat anodized piston resists the kind of corrosion that slowly eats away at lesser components, especially in saltwater environments. The aluminum cover holds strong season after season, even with heavy use. And because it’s built to Mercury’s exact specifications, the fit feels natural — no forcing, no adjustments that leave you second-guessing. Just clean installation and dependable operation the way it’s meant to be.

Why Buy OEM

When you’re dealing with shifting components, shortcuts rarely pay off. A genuine Mercury Marine part like this one gives you the peace of mind that it will fit correctly and work the way the engine expects. Aftermarket parts may look similar, but the internal tolerances and coatings vary, and that can make a huge difference when every shift counts. This part number exists for a reason — to match Mercury’s system perfectly, provide long-term reliability, and save you the cost and trouble of premature replacements. If you want a part that lasts, this is the route seasoned boaters trust.
