I'm looking for info on removing the steering wheel on my boat. It's rack steering on my o/b and a Morse steering system. I removed the center cover and the nut. It looks like there is a tab or key in a groove (hard to see) in the shaft. Tryed to pull it off but don't want to break the wheeel. Is it just very tight? Should I tap on it with a hammer?<br />Any help would be great.
