my 93 Yammy 115 was installed with the 2 guages. One has the tach, trim and oil warnings, the other has ancillary things - seems to have a temp icon, a trip metre a clock and a fuel icon with level indicator. I take it the fuel is for a yammy sender that would sit in the tank (its flashing, but I have no sender to tell it not to - i should just disconnect the plug on that sensor - I have a Navman fuel flow meter) but I was wondering about the temp symbol - does it just flash when the heat alarm goes off or should it give me reading when I set the mode to it. Does that make sense? Thanks
