🔌 Function

The port and starboard brackets form the main structural attachment between the outboard and the boat transom. Together they carry engine weight and thrust while locating the tilt tube, swivel bracket, steering linkages and trim system.

⚠️ Common Signs of Failure

• Cracks around transom-bolt or tilt-tube locations
• Severe corrosion, pitting or loss of casting material
• Elongated mounting holes or damaged threads
• Port and starboard brackets no longer align with the tilt tube
• Bent castings causing uneven trim or steering movement
