The tilt system of an outboard motor relies on hydraulic cylinders to raise and lower the engine. After prolonged use, the cylinder seals may fail due to aging, wear, or corrosion from salt spray; this leads to hydraulic fluid leaks, a drop in system pressure, and the engine failing to maintain its set position or moving sluggishly during operation

This kit contains a complete set of seals and associated components for three hydraulic cylinders, covering piston rod seals, cylinder end cap seals, O-rings, and more. A single purchase provides everything needed to complete the entire seal repair, preventing interruptions to the maintenance process caused by overlooking a small, missing seal

Installing this seal kit to replace failed original seals restores full functionality to the tilt and trim system. Specifically, the engine's lifting and lowering speeds return to normal, no abnormal noises occur during movement, and—once the control button is released—the engine remains stably locked in its set position without slowly drifting downward or rising on its own

The actual contents of the package are as depicted in the product images. Before purchasing, please verify that your outboard motor model and system type are compatible with this product. Note that this kit is *not* Fit for Yamaha 200–300 HP four-stroke models, as those models utilize a different sealing system
