The engine has a little over 1000 hours of operation. He went very well until the end. After switching off in port, the engine only started with hand throttle. If you put the hand throttle back down, the engine stops.

Mercury's diagnostic device indicated lack of gasoline and throttle position sensor as a fault. A new sensor was installed. Now the diagnostic device no longer shows errors. But the problem is still not resolved. The engine only starts with hand throttle and stops when the lever is closed. It is not possible to take a gear.
