well, I'm not sure. I removed, lubed, and replaced the rudder the fall of that year, but it was too late to try it on the water. I sold the boat the following spring (two years ago), so I never had a chance to try it out. I now have a '92 PS 205 that steers just fine.
If the steering on the '89 remained stiff I would have replaced the steering cable; a common fix.
