I haven't drove a gator without it so I don't have anything to compare too. It's smooth. When I first got the gator the power steering made a mechanical ticking noise when you turned it to the left. JD replaced the whole unit right away. It still worked good, just had that ticking.
here is my 2014 GATOR LOTS OF EXTRAS MOST OF WHICH I FABRICATED MYSELF , SNORKLE, AIR INTAKE FOR CLUTCH AND BELT FRONT BRUSH SCREEN AND LED BACKUP AND INTERIOR LIGHTS , 2500 # SUPER WINCH, AND A LOT OF EXTRA LIGHTING
the Radios I have in my Gator is a CB and a Ham radio , the CB I used to communicate between vehicals and the Ham radio I use for emergency communication has far more power then a CB don't know why you thought it was a marine radio that is a completely different band 2 meter band is the most popular for local communication and has the function to reach repeaters if needed, the marine band is prohibited for use on land, and there is a stiff fine if the fcc happens to locate you using it. hope this info helps
