Throttle will not reease back to idle
The throttle on a Mercury 40 may not return to idle because the throttle cable can get bound if the idle speed is changed without readjusting the throttle cable. When the throttle linkage binds, it can prevent proper throttle movement and affect shifting at the driver's console.
