Question about Tach:

[Frankcici]

I have a 2005 Gulfstream with a Yamaha 225 4 stroke runs great. Question: My Tach only records RPM and hours, the other features (oil pressure, temperature and Trim) dont seem to be working/registering wondering if anyone had similar issues and what the remedy was? Before I invest a few bucks on a new gauge wondering if there were any others with similar issue.
Thanks!

when you first turn on the ignition, the gauge goes through a self test where all possible segments of the display 'light' up. Do you see bars above the lower symbols for temp and oil?

No only the rpms and hours light up. ,nothing else

No trim indication either during self test?
If so, looks like gauge is shot.
