Propeller Protractor

Product Features

This universal propeller protractor is a device used to measure the propeller blade angle at a specific blade station and determine if the propeller is properly adjusted.
The blade angle is referenced from the propeller plane of rotation, which is 90 degree to the crank shaft centerline.
The frame of the protractor is made of aluminum and has three sides which are 90 degree to each other. A swing out level is located in the lower corner to assist in determing proper vertical line.
