Although I can not give you advice on boat control because we just run a canoe, and your lucky cause I have always wanted to fish the mississippi in the area that you were describing!
We fish the Crow river a good amount. We have caught many catfish along with pike – walleye – and smallies, however they do not seem abundant. We are able to work pretty slowly upstream with just a 30 thrust trolling motor, however, the crow does get very shallow in some areas, so be careful.
If you looking for some good smallie action, i would recommend the rum river, which dumps into the mississippi in anoka, and I have seen many people with their boats out there, we usually start more north (isanti, st. francis, etc)
