Re: adding a tach to a 25hp mercury 2 stroke El
Sixers, do you have a remote or tiller? If you have the remote, you may already have the tach connection on the wire harness (near the throttle). I put one on mine, a teleflex, and all I needed was a harness adapter ($12.00) and it hooked right up. I have an '03 25hp EL remote and for that motor the tach setting is 4 pole. Let me know. Mike
