What EXACT display or instruments do you have–Let me “SEE” your dash or helm..

 

Are you saying you DO NOT have a full digital display and all you have is a TACH with a “blinkcode window” ?? IF SO, you are not in good shape as it’s close to impossible to troubleshoot anything.. Smartcraft is bad enough, but without a full display, I would have no clue what may be going on.  

 

Think a bit–Does it seem to be worse when the fuel in lower in the tanks?   Tony
