yamaha gauges

[dino1]

Have a 2001 cobia center with Yamaha gauges. RPM and speed with gas. Is there a way to repair, they are digital and have power to them, just not reading?

Having said that, just because you have power going to the gauges and they are not reading anything doesn't mean they are bad. You need to make sure they are receiving the signals from the engine's ECU or other source. Your speed is typically measured by a pitot tube on the leading edge of your engine or by a separate device on the bottom edge of your transom. The hose from the pitot goes straight you your speedometer. RPM's are measured by a signal from your ECU or stator. Your fuel gauge uses a resistance reading from a float rheostat in your fuel tank.
