Re: Switches? Starter, Kill Switch, etc.
Outboard engines have a magneto ignition which means the magneto provides the electrical power and is part of the ignition system. The battery in a magneto system is not even needed after the engine is started. It is used only to spin the starter. Your car and I/O engines have a battery ignition system where the battery provides the electricity for the starter AND the ignition system. Because of these differences, the ignition switches are different. Magneto ignition requires that the ignition switch have the two "M" (magneto) terminals OPEN to allow the engine to run. The engine stops when the two "M" terminals (one of which is grounded) are connected thus shorting the magneto to ground killing the engine. The emergency kill switch is just another switch in that same system. On a battery ignition, +12 volts is always present on the "B" (battery) terminal on the ignition switch. The ignition system is energized when the key is turned to RUN at which time the "B" and "I" (ignition) terminals are connected. The engine dies when the key is returned to OFF sinice there is now no power to the ignition system. You need the correct ignition switch for your engine.
So lets get this right! Do you have the control box (shift/throttle)? If so, the switch is already there. I guess we need to know what you have, what you don't have, and what sort of boat this setup is on. You cannot have just one push to start and one push to choke switch. You would also need a push to stop. That also leaves the boat a prime target for theft.
