My '98 (rotary helm) is a 3/4"... this wheel (the 18" model), at dclark's suggestion, works great:

Also, on the topic of wheel pullers, I'm hoping someone can reassure me that I am not a moron... when I was installing my autopilot (and replacing the stock wheel with the above mentioned 18"), the old wheel would not budge. So, I headed down to the auto parts store and bought a steering wheel puller.
When I got back to the boat, I sat there for about 30 minutes trying to figure out how the darn thing worked (there were no instructions included). It consisted of a large center bolt that was clearly designed to push against the steering wheel shaft, and a pair of smaller bolts that appeared to be intended to screw into holes in the hub of the wheel (which would then be used to pull the wheel out). My wheel did not have any such holes, and, despite plenty of experimenting, I could not figure out a way to utilize this tool in getting the wheel off.
I eventually gave up and went to Sears... they had steering wheel pullers too, but they were pretty much just like the one I had already bought. I then spotted a gear puller, consisting of a large center bolt, and a pair of "hooks" (for lack of a better word) that would grasp the back of the steering wheel hub and pull it when the bolt was tightened. This worked.
So, when everyone here says "get a steering wheel puller" do they really mean get a gear puller? Or is there a way to get the above described steering wheel puller to work in this application?
