Evinrude 50 Reverse Problem


My Evinrude outboard 50 is not responding in reverse -- it slips out if I give it any amount of gas. It barely works at idle speed.

I'm guessing the clutch dog is causing this. Do you know if I need any special tools to realign the lower shaft and gear assembly after I repair the clutch? If yes, where do I get the tool?

Thank you,




If your gearcase is slipping out of reverse like you say, the damage is done and the reverse gear will also show damage. 50% of the time we have been able to remachine the clutch dog contact area (in the gear) to the original "square" shape. Your machinist can tell you upon inspection. There is no tool to "realign" the shaft as it only goes in one way. The only shimming involved is the pinion height and you are not changing the gear set so far. Change the clutch, machine the reverse gear, and after assembly make sure the F-N-R spacing is correct in your controls. The problem should go away and stay away.
