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 compatibility with your engine model before purchasing. You will receive: - 1 piece 5-inch (approximately 13.2 cm) crossbar protector support - 2 pieces 4-inch (approximately 10.2 cm) outboard motor locks These components help keep the engine tilted and stable during transport. The crossbar protector absorbs shock, enhancing trailer safety. The crossbar protection brackets and motor locks install quickly and securely around the trim and tilt mechanisms. They help protect the outboard motor and reduce stress on boat crossbars—especially important when traveling on rough roads. Made from high-density rubber, the components resist heat and corrosion, supporting long-term durability. This set helps prevent crossbeam stress and cracking by redistributing motor weight to the trailer frame. It reduces long-term hull damage, minimizes vibration, decreases internal engine wear, improves traction, and extends motor life. The crossbeam protection support and motor locks lift the motor to avoid contact with ground obstacles such as curbs, potholes, and uneven terrain—ideal for long-distance transport, gravel roads, and sudden stops. Locking the motor angle reduces hydraulic pressure during tilting or trimming, helping prevent fluid leakage and premature component failure.
