I have a 91 PII and I read somewhere on here about holding in the mode button to display the engine hrs, my question is does this work for a 1991? I held it in for at least a minute with no luck . thnx mark
If the boat is Smartcraft equipped it has an hour meter, if not any Mercury tech. can plug up to the engine and read the hours. Smartcraft is the only “gauge” which Merc uses to display engine hours that i know of, but im no expert !
