Re: ICON 7.0 CTS Doesn't Show Fuel

Re using an analogue input for an OIL tank: maybe in the G2 engines there are resistive oil tank level senders.

For legacy oil tanks, I think you have to buy and install a resistive sender to get oil tank level. Usually Evinrude sells them with a NMEA convertor as an oil tank level kit.
