My first boat was a 20 footer too also and it took me a while as a newbie to learn how to operate it. It was white knuckle every time I docked
My advice is to go slow and learn how to use the snifter to maneuver. Practice bumping the motor in and out of gear to control speed especially at slow speeds
Remember that a boat doesn't steer like a car, responds slowly so take small actions and wait to see what happens. The boat can't for the most part be steered if the prop is not turning. That boat will also not turn a the front like a car, it will rotate around a point somewhere near yo at the helm.
The 208 can bow steer significantly in certain conditions so be aware that if the bow id down and you hill swells or wakes, the boat will probably make somewhat sharp and unexpected turns. Over time you will learn when to expect that and how to avoid or deal with it.
Assuming you have a regular rotation motor, when in reverse, the stern will move backwards and to starboard. At the same time, the bow may swing to port. Again, go slow and practice in calm waters to see how the boat responds to power and steering.
Best of luck!
