125 evinrude no reverse

[Randy Loveall]

I have a 1971 125 hp evinrude during the summer use my outboard started clicking when it was put in reverse. The last time out the engine would not go in reverse does fine in foward. So I talked to a couple of people I was told to check cables and if I took cables undone I should be able to put it in nuteral and adjust. With cables undone I canot get it in nuteral my prop will spin in one direction but not both seems like something came loose. Can you help me

Probably have to take gearcase apart and check shifting parts.
