I have a 2000 200hp opti but the gauges have discoloured !! Can you plug and in or do they have to be a certain gauge to match up with the year of motor !!
I was going to retrofit Smartcraft to my 2005 Mariner 115 (yamaha heart beating inside it) and kept getting conflicting opinions.
In the end I just e-mailed Mariner Uk and got a clear answer within 24hours.
Might be the easiest way of avoiding any mix up.
