Rubber crossbeam protectors and trailer motor locks are designed for single hydraulic cylinder trim and tilt systems on outboard engines. Compatible with most marine engines; please verify your engine model before purchasing. You will receive: - 1 piece 5-inch (approximately 13.2 cm) crossbeam protector support - 2 pieces 4-inch (approximately 10.2 cm) outboard motor locks These components help keep the engine securely tilted and stable during transport. The crossbeam protector absorbs shock, enhancing trailer safety. The brackets and locks install quickly around the trim and tilt mechanisms to protect the outboard motor and reduce stress on boat crossbeams—especially helpful on rough roads. Made from high-density rubber, these parts resist heat and corrosion for long-lasting performance. This set helps redistribute motor weight to the trailer frame, reducing stress and potential cracking of the crossbeam. It also minimizes vibration, lowers internal engine wear, improves towing stability, and extends engine life. The supports lift the motor to help avoid contact with the ground, curbs, or potholes—ideal for long-distance transport, gravel roads, and sudden stops. Locking the motor angle reduces strain on the hydraulic trim/tilt system, helping prevent fluid leakage and premature component failure.
