No more jerky shifts. Smooth as silk now!

The zinc coating resists corrosion beautifully. After saltwater exposure, the unit looks and performs like new. Shifts are crisp, and the prop spins freely. 10/10!

The zinc-anodized bolts haven’t rusted after weeks in brackish water. Installation was tool-free, and the unit outperforms my old OEM part. A must-buy for saltwater boaters!
