Changing the direction of the propeller rotation, SP drives
On the propeller hub there is a ‘L’ for left hand rotating and a ‘R’ for right hand rotating propeller. Also the size of the propeller is stamped into the hub, for instance 15×19 where 15 denotes the diameter in inches and 19 the pitch, also in inches. This is not valid for Duoprop propellers.
The sterndrives are supplied adjusted for left hand rotation ‘A’. In some cases, however, it can be of advantage in a twin installation to have right hand rotating starboard propeller ‘B’. It’s possible, by a rather simple adjustment, to change from standard left hand rotating propeller to a right hand rotating one by simply moving the shift rod from ‘A’ to ‘B’. Check to make sure that the adjustment of the retaining pawl and the shift mechanism is still intact. Install the shift mechanism cover. NOTE! There is no need to alter the direction of rotation on the Duoprop sterndrive in a twin installation.
The pitch is the theoretical lengthwise movement of the propeller during one full turn.
