Leave Big motor down?

[dubob]

I have a new boat to me, comes with kicker trolling motor, should I leave the 115 Outboard down or lift it?2nd question, when stored, should outboard and kicker put in the down position or up?  When trailering always up to protect prop and put the weight on the lock mechanism.

I leave my 150 down while trolling.  It helps to keep the boat track true.  I set the electric up front and the kicker in back straight ahead as best I can.  Then I trim to actually go straight ahead with the big motor.  After that, the steering wheel is never touched and all steering is done with the electric motor up front.  Others bring them up.  It really doesn't matter one way or the other.  

At home, both my motors are left up unless in winter storage when they are left down.
