Anybody ever used an electric trolling motor to push a canoe upriver?

I put 50lb/thrust motor on a 13ft canoe and my goal is to be able to go upstream like 2miles. It's a smallish, calm river-average streamflow for this time of year is 5,500 cfs(whatever that fuckin means). Can anyone tell me if that's feasible??

Boat will be loaded with <400lbs
