Pulling Cranks in the River

I could use some tips on how you pull crankbaits in the river. Here in Montana I fish the Missouri below Great Falls. The water is from 5 to 10 foot max in the bigger holes. I run a 90Hp Jet on a 19 ft Roughneck I have an electric motor in front. Right now the river is real mossy.
Do you slip the river. Troll up ? Use the gas motor? Use the electric etc….. Thanks in advance for all your help.
