The motor engages with tight, secure power—no lag, no hesitation—just the clean performance you want when adjusting your outboard in changing water conditions. The fitment feels natural, making installation straightforward even for boaters comfortable doing their own maintenance.

The copper bushings reduce friction and keep movement consistent, while the epoxy-coated armatures protect the internal components from moisture, heat, and corrosion. These features help the motor resist the harsh realities of the marine environment: salt spray, constant vibration, long idle periods, and heavy use during the season. With this part, your trim system works the way it should—reliable, smooth, and ready every time.

Why Buy OEM

If you have spent enough time on the water, you know that trim and tilt reliability is not something you leave to chance. Choosing a genuine Mercury Marine part means choosing the fit, performance, and durability your engine was built for. Aftermarket versions can look similar, but they often lack the corrosion resistance and torque strength required for dependable service. The Mercury Marine part number 8M6007521 is crafted to meet true original equipment standards, giving you long-term confidence and fewer headaches. It is the kind of investment that pays off every time you head out.
