Yep it's just how it is. trying bumping the speed up just a bit, and learn to modulate the throttle both in forward and reverse when docking. Remember in reverse you only really turn to the right. Left turns in reverse are tricky at best and will take some time to learn.

Remember you now have a rudder not a lower unit where the force of the prop is directional. You need movement to make a turn now.

On the docking thing try to remember your limitations and set yourself up for a smooth landing before approaching the dock or landing.
