I found a picture from LongJohn from 2013 showing the cam arrangement at the front of the motor. Sorted the matter in seconds!!!
I actually had my boat in for service the other month and the Mechanic noticed the lack of tilt but didn't even try to sort it, just said he knew you could adjust it somehow!
Anyway, thanks for the info I really appreciate it. One less thing to worry about this coming season whilst on its mooring.
