If I counted the number of new or replacement tachs I ever installed, I bet it would be over 40 ... guessing 37 of them being Teleflex, 2 Faria and with only 1 original OB maker OEM installed (OMC). I bet you Teleflex or Faria makes the gauges for the OEM companies anyway ...
I have found Teleflex to have the widest color/style assortment and availability.
