I am new here, at least posting and am hopeing for some advice and help. I am working on changing the water pump on my 1984 Mercury 115hp L6 outboard and I am having a hard time determining which shift design this motor has. The manual says to put it in reverse and turn the prop counterclockwise and see if it rackets. When I do this, it turns about 1/4 of a turn and then stops. It will click once and then turn normal for a little bit farther and then stops. I need to figure this out to know which gear to place it in when I drop the lower unit. Any and all advice would be appreciated.
