    Hello! I have a hard one for me at least. I'm making a duck hunting system that needs to run on its own off of a 12v battery. I need a water proof motor if possible. But I need the motor to run for 10 to 15 seconds and the reverse and run the same amount going the other way. And so on and so on. I can use a trolling motor off a boat if needed. Can anyone help??? Thanks!

    You could use a 555 timer that drives a DPDT relay which, in turn, reverses the direction of the motor.

    Google for "555 timer relay circuit" and for "reverse motor with relay" and you should get quite a few ideas.
