Re: bell housing issue
If you mean the funky looking shift link that resides inside the bell housing and sticks into the upper housing, here's how. There is a tiny little piece of stainless wire that keeps the set screw from backing out and being lost. Remove that, remove the shifter end inside the boat so there is nothing but a bare cable-end in there, then pull the cable through from the boat out through the transom plate..
Or more importantly, why are you messing with that. It is a pain in the derriere to reinstall. Look it up in manual #6 of the tech help stickies.
If you are doing a shift cable get a Craftsman spark plug socket with a hex on it's back end. Then use the next size up deep socket on top of the first socket for the shift cable installation. This avoids welding together two sockets, you just use tools that anyone might use or need.
