I had a rudder on my boat for about a month last summer, and then removed it. It helps a lot in the slow, no wake zones. But I kind of like sliding around at top speed, a feeling you can only get in a jet boat. My rudder was the big one, ordered it right from Place. It was also a major pain while my boat was on the trailer. I always had to be extra careful when entering or exiting gas stations, driveways, parks, etc. My trailer is pretty low and the rudder made it even lower. Leave it off. Only my opinion.
