Outboard propellers are fitted with an inner hub made of a material designed to shear away upon heavy impact, and so protect the drivetrain from shock damage. When the hub shears, it's known as " spinning the hub .". Usually, there is enough friction with a spun hub to allow you to operate the engine at low rpm.
What causes propellers to corrode?
Corrosion. One of the most insidious causes of propeller damage is corrosion. This includes external corrosion that is visible on the blades, as well as internal corrosion that literally eats away at the components within the hub of a variable-pitch propeller. Regardless of its location, corrosion reduces the structural integrity ...
What are the most common forms of physical propeller damage?
The most common forms of physical propeller damage are nicks, dings, and cracks on both the blades and the hub of the propeller .
