Wiring up the push button as an remote / emergency
start is an excellent use of the switch.
Wire the switch directly between the battery
stud on the starter motor
and the ignition key terminal on the starter solenoid. This will bypass the existing key switch, wiring harness, and neutral safety
switches, and ensure you have an alternate way of starting the engine in case of failure of any of the above items.
I recommend adding a protective surge suppressor diode at the engine alternator
, just in case someone accidentally starts the engine with alternator
output disconnected by the battery
switch. "Zap Stopper" is one brand name of suppressor.
Also, consider the position of the transmission
shift lever before starting
the engine with the key bypass button. If the engine is in gear
, the boat may move in an unexpected and undesirable direction!
Relocate the button to a not so obvious position inside the engine compartment to keep it away from children
and other unauthorized persons.
