Changing the direction of the
propeller rotation, SP drives
The sterndrives are supplied adjusted for left hand ro-
tation ‘A’. In some cases, however, it can be of ad-
vantage in a twin installation to have right hand rotat-
ing 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 mecha-
nism cover.
NOTE! There is no need to alter the direction of rota-
tion on the Duoprop sterndrive in a twin installation.
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 Duo-
prop propellers.
The pitch is the theoretical lengthwise movement of
the propeller during one full turn.
