Since last season Iv'e been fighting the teleflex sync gauge with no solutions. I've checked my tachs with an optic tach and they check out ok .Replaced boat sync module and gauge and this didn't resolve the problem.The gauge works fine for awhile at 3,200 RPM then the needle goes to the peg on the starboard side and stays there.Voltage meter readings at the gauge reflects this.If you let the boat sit over night the same things happens.Talked to the Teleflex and they say its a bad module but they can't tell me what caused it to fail.
