Re: Yamaha multigauge speedometer
I tried cleaning the pin hole out in the lower unit with a drill bit , went in about an inch and a quarter, gauge still not working, disconnected the hose from the clear hose in the engine crowling and disconnected the clear hose at the gauge and ran auir through and it was clear. Did the same at the pin hole on lower unit and no air came out of the disconnected end which was connected to the clear tube to gauge. The clog is obviously in the black tube in engine connected to oin hole. Ant suggestions as to how to clear this hose which is black in color.
