I have a year Model 2000, Yamaha 200 OX66 on my 22 ft Century CC. I have a Dual Motor Yamaha Fuel Management guage setup that came in a box with this boat. The boat has 1 motor and will never have more than 1 motor. Can I install this Fuel Management guage on my boat or do I need a "Single" Fuel Management guage? Can I just use the Port or Starboard side of this guage, I hate to waste this resource, It is new in the box.
