Defining and checking pitch adjustments
It is quite possible to set the pitch continuously variable and independently for forward and reverse. The
turning of the adjusting screws (2) & (4) in Figure 2
&
3a ( see pages 5&6 ) by half a revolution changes the
pitch approx. 1“.That means a quarter turn ( 90° ) changes the pitch by ½” and a one full turn by 2” etc..
For a check of pitch adjustments there are markings on the hub face under the zinc anode.
To return to original factory pitch settings, line up
“AH” or “V”
resp.
“AS” or “R”
markings on the hub face.
Example:
check adjustments ahead
inner marking has moved
original factory pitch setting pitch has been increased ahead
ahead
check adjustments astern
inner marking has moved
original factory pitch setting pitch has been decreased astern
astern
Note :
If the engine does not reach the desired RPM reduce the pitch.
If the engine exceeds the desired RPM increase the pitch.
1” of pitch reduction / increase results in approx. 200 engine revolutions increase / reduction.
