If your buying both motors, you can pick and choose which gets the counter-rotating lower unit. They are interchangeable (shift cable would need to be reversed at the control box for counter). There are a lot of props for a left hand lower, I don't think you are too limited there..
Opti's figure fuel burn down to molecule so with the Smartcraft you can get Trip in miles, average MPG, instantaneous GPH and MPG in addition to volts,engine tilt, engine temp, speed, water pressure, barometric pressure, water temp, outside air temp, hours, oil tank level,fuel level(with optional sender) trolling speed function is configurable as well. They have several gauges avail, the typical tach and speed gauges are the most common, each one has a analog sweep plus a LDC display at the bottom OR they have a single gauge setup that is all LCD OR they now have vessel view monitor that is like a chartplotter for your engine with a color display. The sky is the limit... You decide on how much info you really want or need for the $$$.
