Cables & Drivetrain
On a cable lift, everything between the motor and the cradle is the drivetrain: gearbox, drum, wire rope and sheaves. It is also where most failures that drop a boat begin. A cable rarely snaps without warning; it shows broken wires, rust bleeding and flattening for months first.
Learn what a healthy cable looks like, how long cables last in your water, and how to replace one with the load safely supported.
