I have a 1974 Evinrude 135 hp Model # 135489B Serial # J0001788.<br />I am attempting to connect a tachometer but can not find the terminal or wire to connect to.<br />Does anyone know where on the motor the connection is?<br />This motor was just installed on a different boat and I would like to get the tach working so that I can find the right prop for the new boat.<br />Any suggestions would greatly be appreciated
