Greetings to all from Turkey where I am with with my 85 year old sailing friend on his boat.. a 1973 Taiwanese built double ender .. a Traveller 32. We have sailed together for many years.. trouble free till bow.

We have the Sabb model G with a Variable pitch propeller arrangement.
Our problem is as follows:

The shift from forward to reverse has become very stiff.

I have removed the 4 bolts between the Flange that connects to the propeller shaft coupling ( part number G82BC )…. Now , not being connected it is very easy to change from forward to reverse…

I can spin the propeller shaft but not push it out or pull it in at all.

We suspect the problem is in the Propeller boss… the housing holding the propeller blades that controls the pitch.

Do anyone have any exploded diagrams that might help us ( other than the ones in the green handbook ) or any advice.

Also can the Propeller Boss housing be removed while in the water.. ?

I have attached a Picture of the same motor and propeller as we have.

Many thanks for reading,
Mike.. Sailing boat BOGLE Traveller 32 ( plenty on our Travels in Eastern Mediterranean on YouTube )

There is a hand screw directly above where the shaft exits the gearbox that "locks pitch control". You could check that this is not tightened down. I leave mine loose, because I never find the need to lock the pitch control. See item # 16 in the attached excerpt from the Sabb Model G manual.
