Basically what is happening in both these two methods are doing the same thing, meaning the switch closes-not opens(the voltage is dropped to a point that the engine cant run by taking the 12 volts to 0 volts by shorting it to ground. BTW i wouldn't tie the aluminum boat to the ground of the battery.Just my 2 cents worth.
