The remote box (with the handle) is really pretty simple. It handles gear shift and throttle in a coordinated way to ensure you engage gear at the right (low) rpm.


The connected rods and links in the motor are set up to ensure that gears are engaged before adding throttle etc.


Before diasassembling the box:

Look for kinks and cables needing adjustment. If no obvious solution try disconnecting the cables at the motor and move the levers by hand.


Then turn to the box.
