I have a 1988 Celebrity 210V Cuddy, on which the dash gauges are slowly dying. Right now I am in need of a Tachometer and a temperature gauge, but figure it won't be long till they all die. These gauges are flat and mount inside the dash against a sheet of plexiglass. Local boat places say they were probably specialty items ordered by the boat manufacturer, which is out of business now. Anyone know where I can find replacements?
