In fact your new merc monitor can be set up to display 2 tanks, or at least the twin engine model can. The wema senders would have to be connected to the monitor via a mercury boat harness if you haven't got one already.
Ps "wema" in predictive text comes out as "enema" - always pays to check before hitting the send button )

Lowrance 200 or 400 will only display nmea2000. The simplest might be to get a pair of converters to convert the resistance data from your senders into nmea2k data. You could then feed that into your lmf gauges or plotter.
