    2017 Z19 Spedo/Gas guage stopped working

    My Spedo and gas guage stopped working. Do these have separate fuses per guage? Just not sure where to start.

    The speedo is literally a tube from the lower unit to the dash, water pressure pushes harder. No electronics. Look at the lower unit from under the step of the hull, there is a small hole this can plug with wood or weeds, ask in the mercury forum, also just up some there is a plastic air tube to connect to the rest of the system

    Fuel gauge, I'd look under the center seat to investigate wires, then I'd investigate under the dash

    Thanks Fishy! I know the spedo deal. Thats been clogged up a while. Its one plug in the back of the guage tho which tells me both spedo and fuel is an electronic reading?

    2 fairly useless gauges. The fuel does give u an idea of where your at. Doubt there is one fuse just for the fuel gauge, any others out? def check wiring.
