6.4 HOW TO KNOW THE VALUE OF THE PITCH
SET ON YOUR PROPELLER
If the two screws/rods have been both completely screwed up to abutment
in its housings, the forward and the backwards motion pitch of the propeller
correspond to the numbers stamped on the respective screws/rods.
If the screw/rod is not completely screwed up to abutment in its housing,
proceed as follows to know the value of the pitch:
PRACTICAL EXAMPLE CONCERNING
THE FORWARD MOTION PITCH
The screw/rod stamped number 22 has been screwed into its seat up
to abutment, therefore the propeller has a forward motion pitch of
22°. Starting from the stroke position of this screw/rod, if you loosen
three grooves of the screw/rod, the propeller pitch will decrease by
1.5° (0.5 x 3 = 1.5). The propeller will therefore take a new forward
motion pitch of 20.5 ° (22 - 1.5 = 20.5).
PRACTICAL EXAMPLE CONCERNING
THE BACKWARDS MOTION PITCH
A screw/rod stamped number 1 has been screwed in its seat up to
abutment, therefore the propeller has a backwards motion pitch of 16
degrees. By unscrewing the screw/rod of three grooves, the propeller
pitch will increase by 1,5 degrees (0.5 x 3 = 1,5). The propeller will
therefore assume a new backwards motion pitch of 17,5 degrees ( 16
+ 1,5 = 17,5).
interval between one groove and the following one of each backwards pitch
adjustment screw/rod will increase the backwards motion pitch by half a
degree (4 : 8 = 0.5).
