I am new to boating and have a question about steering. On my R160, I am able to turn my steering wheel in either direction without it locking like if you were in a car and turning the wheel. Is this normal? Should you eventually hit a locking point? The motor does response when I I turn but when I hit the max turn, right or left, I am still able to turn it. It feels a little stiffer but I am still able to rotate. Thanks for your insights.
