I have been thinking about adding a tach to my '85 Merc 90 inline 6 outboard. Are there any aftermarket tachs that will work these engines and don't cost several hundred bucks?
i bought mine from a local marina for 30 dollars. its a smaller 2 1/4 size, not the big 3 1/2 size . go to any westmarine or boatersworld and get one for 65 dollars
