Re: 84 15 hp Evinrude How to remove the tillers gears.
The one in the handle is held in by a screw that goes through handle.(Rubber grip may have slipped feel around for a hole and reposition grip as required).
The motor side has a retaining ring holding it on the back side of gear...its easy to remove and a bit of a game to put back on.
Hope this helps and good luck.
