If a Quicksilver OUTBOARD tack with a 6pulse setting, you may use it.

Re: johnson tach question

Tach shouldn't put any inputs in a motor's electric system. The only connection to the motor is via the pulse wire (grey wire in your control). As the previous poster said, as long as its a 6-pulse tach, you are good to go. Wire power to your dashboard, grey wire in the control is the signal.
