Wow, thanks Simon!
I had a look in that area today, that picture certainly fill in the spaces for me, thanks again. So you have a linear drive, is that favoured over the rotary drive type? I bought a lewmar drive kit complete with chain for mine, it fitted in on the AP sprocket and 4 stud mount perfect. I am guessing you fitted your set up yourself, so where did you mount your motion sensor and control unit? I am tracing the original wiring from helm station to the saloon area, and hoping I can route my cables through that passage, fingers crossed?
Cheers Richard
