Hi Steve,
The "Bow Down" postition moves the tabs down too. This causes an upward force on the stern, thus pushing the bow down...
But, do you have regular switches or those with the indicator LEDs next to them?
For the normal ones, go for the "Bow Up" position.
For the indicator switch type, you don't have to do anything as the tabs come up all the way as soon as you cut the ignition.
