“Most LED indicators have less then 17 lights, and even systems like SmartCraft or Garmin have only 100 steps in their displays to indicate the position of the drives/engines,” he said. “The problem is that the range of motion for the propeller shaft on a stern drive or outboard from full down to full up can be more than 23 inches.
