2004 Johnson, 115hp 2 cycle.
I replaced the impeller and now reverse and neutral work fine but when shifting into forward the gears chatter but don't grab. I did set the height but it must still be off a bit. Should the shift rod be raised or lowered, and if so by how much? And is there any way to do it without taking the lower unit off again? Thanks for your help.
