1. A method of operating a marine drive configured to propel a marine vessel, the method comprising:
operating the marine drive to effectuate a specified heading based on a steering input;
measuring a heading of the marine vessel using a heading sensor;
measuring acceleration data of the marine vessel using at least one sensor:
determining, by a processor, that a heading error between the specified heading and the measured heading exceeds a heading error threshold;
classifying the heading error based at least in part on the measured acceleration data during a time period associated with the heading error exceeding the threshold; and
performing a heading error response based on the heading error classification.
