My son bought a nice little Smoker Craft 14' Jon Boat with a 1981 Evinrude 25hp tiller on it. Motor starts first crank and ran out great. Was always difficult to get into reverse. Last time he used it he broke the shift handle trying to get it into reverse. Replaced the shift handle and now can't get it into forward or reverse - see video: https://youtu.be/dQTbTbASZvc Also - I do not see the shift rod moving at all where the coupler is. Any ideas would be much appreciated. Thank you.
