Thread: outboard tach

  1. #1

    I have a 91 evinrude 225 looper, the tach i bought has a seperate connection for johnson/evinrude hookup, but it also has a adjustable setting for 6 , 8, 10 or 12 "pole position. I can find Nothing in manuals about which position I should select. The tachs not working and store guy was guessing on poles. Anyone know which is correct and what are the poles? thanks

    markr, I too am in the process of installin' a new Teleflex tach in place of the Merc tach on my float. Mine is just a 90HP Merc but if it is referrin' to the same thing as mine, the reference to poles is in accordance to the number of poles on your alternator. My tach is an alternator driven tach; countin' the number of pulses from the alternator. Check with your shop guy (not the salesmen) and see what number of poles your alternator has. It just maybe that that is what is bein' referred to. Hope this helped. BTW, didn't your new tach have some instructions? That should be explained in there somewhere.
