Outboard works fine and will do the trick, be very carefull with the sock and not let it get in the prop.
I remember when I started cranking, man it seemed like a was going to pull the lips off them cranks and not catching nothing. Some lakes are just not good cranking lakes but that wasn't my problem, just had to figure it out. Best advise is to get in a boat with someone who is successful there and pick their brain and watch. I was hard headed and did not do this but it is the best way, how I cut my teeth spider rigging.
Good luck.
