This is my 1st time on this site. I have a 1976 115 v4 evinrude which has been great up till 4 weeks ago. The gear is stuck in reverse and i managed to get it in neutral once. As soon as i placed it back in gear it stayed there and now wont get out. I've taken the lower unit off and have tried to get it out of gear with the shift linkage with no luck. Any ideas would be great.<br />Also what year and model is this lower unit interchangable with the Johnston? eg. 1975 80hp-115hp johnston.
