I have twin Yamaha 150s on my 2000 Islander. How should I set the selector switches for starting and motoring? I have the option of setting each of the swithes to "1", "2" or "both".
I have three batteries and three switches. One switch is "on/off" and powers the electronics, lights, etc. I have two other switches that can be postioned in either "1", "2", "both" or "off".
COOL
1 battery switch is for port and 1 is for starboard
i would run port on 1 and starboard on 2
this way you are charging both the battiers
if they will not start run them on both and start 1 motor first, then the other
