PITCH ADJUSTMENT „RH“ 

 

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.3a. If not, the propeller must first be pulled. ( see removing  
     from the shaft ) 

 
Propeller in the drawing below (Fig.3a) is for a 

right hand

 rotation 

RH.

The following description refers to the view towards astern for a 

right 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” 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. 

The 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.

V= AH  (Ahead)
