i have a 1971 Johnson 50hp. It was stuck in forward gear after researching this site i found how to check it. Upon taking the controls apart i discovered that there is a 3 way switch under the control lever that makes it go from forward/reverse/neutral that is broke and i can't find one. I have heard the you can put a switch on the outside. does anyone have any idea on how to do this or if it can be done. Thanks
