The way the DR worked for Fw and Rv is all timing and engine rotation direction. The control box killed the engine when throttle lever in the middle/idle area then there is a button on throttle lever to start the engine in the direction the lever was positioned. When properly adjusted you can only start it at low speed. When out of adjustment you can start it full speed, 60-85hp in all …This is when docks got “busted” and they became infamous. It is certainly a learned coordination effort.
