The shifting on my 1990 Four Winns got so bad that I had to change the shift cable before the season was over. I lubed up the cable with Ruglyde (tire mounting lube) and was able to feed it through with no help from the inside. I got a kit that had everything, but the bellows and gimbal bearing were fine so I left them alone. I had tweaked my back and didn't want to pull the outdrive by hand so I made a stand. Most of the ones I saw looked too complicated. Hope this helps someone.
