The O‘day 302 does not have hydraulic steering. If it has the same set up as my 322, it will be an Edson steering system…
Lots of threads about AP’s…but only a few options for a wheel pilot…Raymarine or CPT.
If you really wanted to go to the Expense of a below-deck AP, you have more choices, but probably overkill on a 30-ft boat on Lake Michigan.
I had an older Raymarine ST4000+ on my O’Day 322. Worked fine but was getting a long in the tooth. I replaced it with an “open box” ST6002 AP with a rudder sensor. I like the system. Works well even in heavier conditions.
Raymarine‘ current offering is the EV-100. I imaging the computer is better, not sure about the rest… sand it does not have a rudder sensor.
