I went sail-drive because I didn't want to have to deal with engine bed re-alignment. I've done a sail-drive before in a previous boat and I thought it was quite simple. Just cut a big hole in the bottom of the boat (arrrgh!!). I went with the 20 because of the three cylinders. I wanted a smoother running engine and three will be smoother than two. The sail drive system will also help smooth it out. Will you be ready for the July Islander Rendezvous at Telegraph Harbour Marina this year?
