There is an "exit" hole for the grease in the bottom of that housing; forget if it's in front of or behind the rudder shaft. However - it is VERY SMALL. I purchased a hydro locking grease gun end by Lincoln and use about half a tube of grease every time I went to lube it. Eventually it builds up enough pressure and will poop out a very small string of grease on the bottom of the boat via said hole. All of this aside it is an infuriating process to waste that much grease to get 1 oz in the freakin' rudder.

Also, my zirk did not have a bearing in it. When full it would puke a bit of grease back thru the zirk (also pretty maddening) when you rudder full in either direction. I assumed this is to keep the rudder shaft from hydro locking completely. The steering was remarkably improved each time I performed this operation though.

This seems to be the case. Replacing that zerk could be dangerous...

I greased the two zerks on the cable and linkage - no issues. I went to grease the last zerk on the rudder housing and could not get any grease pushed through. I thought it was a seized zerk so I replaced the zerk, however when I went to push grease through the new zerk same result - could not get any grease to go through. SO I removed the new zerk and installed in the grease gun only, no issues and grease came through the back side of the zerk. I assume I have some type of "hydro-lock" in the rudder housing preventing new grease from entering? I also assume this is caused by a clogged excess/breather port? I was holding the grease gun hose on the zerk and had a friend squeeze the hell out of the grease gun - nothing. Does anyone have any suggestions on how to clean out the rudder or port so I can get new grease in the housing, basically remove the vapor lock? Very much appreciated - you guys are the experts - thanks!
Did you get this resolved? Mine also didn't want to take grease and I pulled the zerk to confirm that it was not clogged. I think the grease in the rudder box was so old and gunked up that it had made a seal and wasn't letting the fresh stuff through. I had just bought the boat and have no idea when it was last serviced. I pumped it up until the grease gun popped off the zerk twice, and the third time it blew out whatever was clogging it and fresh grease came out the hole on the bottom. Steering improved a little right away and continued to improve as I used it the next couple times out on the boat.

Your 92 may be ready for a new cable. Been there several times and the new cable usually does the trick.
