Hi. Like the title reads... 74' Evinrude 85hp engine runs like a saint, but will not go into drive....forward or reverse. I'm no mechanic, so what kind of things should I expect when removing the lower unit?? and when I put back together, what other things should I replace??.........This is my first engine, feeling cheap, so any work I can do myself will save me mulah!!...Oh, and since this engine is down, I went and bought another (89'Johnson 110 VRO):facepalm I NEEEDDDD to get out fishing! ):fish2:
