I like to share some of my "improvements" to my SO30i which may be working as well for other boats:
Connecting the Raymarine ST1000+ to the tiller
To make the mounting I bought a "plastic" (PET) block at the size of approx. 10 x 10 x 6 cm
Then took the saw made one diagonal cut and screwed the cutted edge again to the rest.
This new item was then screwed by 4 screws to the cockpit wall.
The very good thing is: nobody hurted himself by now ;-)
