Shaft is a 1" straight shaft with a keyway (Be sure to check yours before ordering)..so a hub that matches that is what ya need. The front-to-back length of the hub is really important, and I don't have that info at hand. Soooo if ya really want a smaller wheel one that satisfies the shaft fit will work. The folding one may be a way to get ease of access when at anchor and still retain the ability to steer while way outboard watching traffic and teltails.. Lewmar makes a good one.
Another option is to have a quick release nut and a bracket to mount the wheel on the pulpit when at anchor.
Thank you!! Edson site has the wealth of specific info to send me on my way! Ilan
