Installing a Vetus flexible coupling
To remove the old stuffingbox and Volvo Blackjack, and to install the new PYI PSS, you need to remove the flexible coupling, that connects the output flange on the gearbox to the propeller shaft.
The old coupling had "grown" into the propeller shaft, which made it impossible to remove.
That´s where the "deathwheel" came into play... read more under/next to the photos.
Anyways - I had to buy a new flexible coupling.
Only the best is good enough, so I bought the Vetus Uniflex.. It fits the 35mm propeller shaft and the Velvet Drive gearbox output flange.
600 Euro later... :-(
