Has anyone had issues with Zero Off changing to speeds that are outside of normal, specifically 70 mph and 50 mph? This happens when sitting idle and fortunately not to this degree when under power, otherwise we would have some entertaining video. We have had it change to 36 as we enter the course when someone is expecting something slower like 26 or 28 and the driver has to quickly change it back. Also fortunately, this does not happen once the boat is up to speed and ZO takes over. When the speed changes to 70 or 50, the speed setting may quickly flash back and forth from a normal speed setting to these or it may simply lock and ZO will not respond to attempts to change the speed setting. We cannot select these high speeds, ZO makes the change on its own. Doing a full shutdown of the boat and killing the main power switch helps, but does not always work. This is on a 2017 ProStar running Rev R on a single puck. Yes, we contacted ZO and they said it was the display or display software.
