Thanks - I tried this and was originally convinced that there was no movement in the linkage - so using your advice from a few posts back disconnected the crank pin from the gearshift rod (although I'm not sure how I'll get to the other end to get it back together) and have taken the lower unit off.
The good news is that when I give the clutch rod a good hard tug upwards to put the gears in reverse, the gears engage and when turning the propeller it doesn't slip at all.
I've now re-looked at the clutch/gear selector adjuster and the shaft is only just screwed into the plastic end piece, which I think allows it to flex too much when trying to put the selector into reverse so it hasn't been engaging properly.
Hopefully the rod can be extended by unscrewing it in the centre (I ran out of time to check this) so I can just put it all back together tomorrow and it will be fixed.
