My rudder broke one time, and using reverse was the only way to steer. Now is when things get complicated. You would think a boat in forward would hold a straight line. No. As the prop spins, it "torques" the boat one way. Usually to starboard. So as I drove a little, I had to reverse a little, drive a little, reverse a little... Less learned, if you get shallow and hit mud, do no back out of it. Get out of the boat into the water, and push it.
