I have an 87 merc 60hp serial # 9474837 and while i have found it to be an excellent motor in terms of reliability and performance on my fairly light rib, now wish to fit the above instrumentation. I have had a look at various web sites including the teleflex one but cannt seem to sort out exactly which sender units I would need.<br /><br />could anybody provide the info that would enable me to identify the senders and gauges that i would need and a us dealer that would mail them to a us address or send them overseas to the uk?
