Or you could forget the motor and "fish from the hip". Some call it bobber doggin' but use a float above your drift gear so that your teminal gear bounces along the bottom every ten or so feet like you were side drifting except in this case you would cast your line out to the slot while your boat is in as shallow water as possible without banging bottom. After you make the cast, sit down on the butt end of your rod while you control your presentation with the oars and the float will do the rest. This works pretty well in small to medium rivers.
