  • Setting yamaha tach for 2 or 4 stroke

    Does anyone know how to set the three small switches on the back of the Yamaha Multifunction Outboard Tachometer for a 2004 2-stroke 90hp. Is there a guide anywhere. I can't find anything in the manual.

    The instructions are on a card that comes with tach, The settings for a 90 are
    swtch 1 "up" (2 lead trim sender)
    switch 2 "up" ( 6 pole alternator)
    switch 3 "down" (2 stroke engine)
