So this is the view of our batteries, in OFF position.
LEAVING THE BAY
Turn the START and the HOUSE knobs 90 degrees to ON position.
Then turn on the engine.
Untie the boat.
And away you go.
Tie up the boat.
Turn off the engine.
Turn the battery off by turning the knobs to the OFF position as shown above.
Only if we had a flat battery would be use the middle knob. That is why it is for EMERGENCIES only.
Why is it called a HOUSE Battery when it is on a boat? It is really for the electronics, like the electric head, the GPS, Fishfinder, lighting and so forth. I supposed I have answered my own question. The boat is the home. Perhaps it should be called the HOME Battery?
Did you turn off your battery?
