no auto will work good at slow speeds I have a older unit that is nmea in it goes on to the steering wheel slow response from all units but the out boards use a lin drive I seen some that will go onto the steer cable but have seen a ton of issues with them coming loose or maring the steer shaft the pump ones are very expensive look for a unit that will go on the wheel very simple to install and use I might sell mine it was on my 24ft but now its just sitting in the storage box of my 29ft not being used
