I have a Johnson 90 with a Morse shift/throttle control. The shifter has felt a little sloppy for a while now (lots of movement between forward and reverse, tough to pull out into neutral). Last night, I pulled the lever out to start and it felt like the whole thing was going to come apart... then it wouldn't go back into gear. With some jiggling, it finally engaged into gear, but I've got the feeling it needs some major help.<br /><br />Can these controls be taken apart and serviced? I asked the last time I had the boat in the shop and they told me that they couldn't do anything but replace it.
