Re: OMC Side Mount Control Manual
The other lever, the one that lifts up, is for giving it some throttle to start and warm up the motor without putting it in gear. Raise it to give it some throttle, lower it all the way to go back to idle. It has to be all the way down before you can shift.
The gizmo with the rope (lanyard) is a kill switch. You clip it to your clothes or life jacket (you do have a life jacket, right), and when you fall out of the boat it kills the engine. Otherwise the boat keeps going, leaving you there to drown. Worse yet, it goes around in a circle, coming back to run over you to make sure you are dead. Don't laugh, it has happened MANY times. The motor won't start or run without the lanyard attached to the switch button.
The key switch is self-explanitory, except that you push in on it while turning it to the start position. Pushing in on it operates the choke or primer, whichever applies. They both do the same thing.
