Checking the Propeller Clearance
Before installing the trolling motor mount, you must make sure there will be enough clearance between the propeller and the hull through the entire rotation of the motor shaft. You must take into consideration potential flexing of the mounting location that may occur after the motor is installed. Installing the motor with insufficient space between the propeller and the hull may result in personal injury and property damage if the propeller contacts the hull during use.

Rotate the propeller drive motor manually to check the clearance through a complete 360-degree rotation of the shaft.
You should check for sufficient clearance using both the high-efficiency propeller and the weedless propeller before installing the mount.
