PITCH ADJUSTMENT „LH“
GERNAL:
The pitch adjustment is very simple on the VARIPROP, and can be done in or out of the water in
a matter of few minutes, if there is enough space between propeller hub and strut to fit an allen
key into the set screws (1) & (3) at Fig.2 . If not, the propeller must first be pulled. (see removing
from the shaft)
Propeller in the drawing below (Fig.2) is for a

The following description refers to the view towards astern for a
left hand VARIPROP

A. Adjusting the forward pitch:
B. Adjusting the reverse pitch:
1.
Remove the set screw (1/ 4mm allen key).
1.
Remove the set screw (3/ 4mm allen key).
Under water: only 3 turns loosen. Under water: only 3 turns loosen.
2.
Turn the adjusting screw (2) which is marked as
2.
Turn the adjusting screw (4) which is marked as
“AH” or “V”
with the 5mm Allen-key as follows:
“AS” or “R”
with the 5mm Allen-key as follows:
2a.
Increasing of pitch approx. 3“ max.:
2a.
Increasing of pitch approx. 2“ max.:
- Turn the adjusting screw (2) clockwise. - Turn the adjusting screw (4) anti-clockwise.
( see “NOTE” and page 7) ( see “NOTE” and page 7)
- Secure set screw (1) with LOCTITE low (pink) - Secure set screw (3) with LOCTITE low (pink)
Lock set screw strongly. Lock set screw strongly.
2b.
Reducing of pitch approx. 2“ max.:
2b.
Reducing of pitch approx. 3“ max.:
- Turn the adjusting screw (2) anti-clockwise. - Turn the adjusting screw (4) clockwise.
( see “NOTE” and page 7). ( see “NOTE” and page 7).
- Secure set screw (1) with LOCTITE low (pink) - Secure set screw (3) with LOCTITE low (pink).
- Lock set screw strongly. - Lock set screw strongly.
NOTE:
It is quite possible to set the pitch continuously variable and independently for forward and reverse.
Turning of the adjusting screws (2) & (4) by half a revolution ( 180° ) changes the pitch approx. 1“. This will
change the engine revolution by approx.200.
