malibu kayak x factor trolling motor experience and rigging

[boxturtle]

So thinking about picking up an x factor and rigging it with a trolling motor. Already have a small skiff for when I go out with a buddy. I want a setup that I can take out myself w/out a trailer. On Fridays I want to just take off from work but no parking for car and trailer. So budget wise the x factor fits the bill.
For those who had one setup with a trolling motor what was your experience? I'm debating on either doing a bassyak like setup in the rear or do that support bar and placing it on the side just behind the seat. The con of it in the rear is if I get kelp tangled up. Also it's more work to setup it up like that. The side mount would be easier and I imagine if kelp get tangled it be easier to untangle. My concern is will having the motor on one side make the kayak unbalance....think I need a counter balance on the other side?
Any input is greatly appreciated.
