I got the cylinder installed on the motor yesterday evening with some help from friend Cory. There was some trial and error involved. The instructions were a little lacking, but all in all it wasn't too bad. A little tight in there trying to get the tiller bolt connected.
For the helm, my existing hole isn't big enough. Referring back to the diagram, my 2 mounting choices are on the left of the picture below. For the top one, a 5" hole is required and 4" for the bottom option. I'm going to start out with the bottom option with the thinking that if I do not like it I will cut it out to 5" and use the top option. Once its cut you can't put it back! I'm going to put a few feelers out today to try and get a 4" hole saw. Either my dad or one of my friends probably has one laying around. If I can't find one I'll go buy one. Working again this evening. Once the hole is cut I'll be almost there. Will post progress.
