I ended up getting all new gauges from great lakes skipper. I went with the white kronos series. I was able to find a dual tach similar to the stock gauge that had RPM for both stbd and port engines all in one gauge (model TCC054a), however I couldn't find a similar 4n1 with trim,oil,volt and temp all in one gauge like the original stock version. I was however able to find a 2n1 that had oil and temp for both engines all in one gauge. then I just needed separate trim and volt gauges for each motor along with a new fuel gauge and speedo to match the others. unfortunately, this required all new wiring and a new dash panel to accept the new gauge sizes and positions. it wasn't that hard of a project, doesn't require any special tools. hardest part is fishing the wires from the motor to the dash.
