Can anyone please give me correct procedure to adjust shift cable to allow engine to go into reverse, new cables have been fitted, I screwed adjuster on cable 3 turns and it ran in reverse on muffs but will not engage in water, it does engage by hand when cable is taken off, control box is original OMC with electric start and choke, I don't want to muck up anything and take out forward gear as we are sweltering here in Scotland in 25c and really enjoying my boating, I have 2 clymer manuals but find them complicated, many thanks JBD
