My Beede tachometer has been jumping from 6000 to 7000 for the last few months. I checked all of the wiring to make sure it was tight on the gauge. I'm having a tough time finding a replacement for it and the closest one I have found has a Honda trim gauge and I don't think it is compatible with a Yamaha outboard. I know other Triton owners have gone through this trouble already. Any thoughts or tips? Pics included
