A hydraulic autopilot handles the steering loads that tire out your arms on a long day at the helm. It pushes and pulls the rudder based on your heading, staying locked on even when the waves try to push the bow off course. Whether you are motoring across a bay or making a trip up the coast, it saves you from being glued to the wheel. Check your steering ram size to make sure everything matches up. It makes a noticeable difference when the water gets a bit bumpy.
