Does anyone know if you can remove an Onan Type 7MDKAV-2317 MDKAV 7 kW 50 Hz Diesel out of a later model SM without removal of the Yanmar engine?  If you have done this would love to here your experiences.

Since yesterday when I tried to park in a box in a marina in Auckland my bow thruster motor failed. 
If I turn the beam to the left or right the whole power supply breaks down for a moment. After that the power is back. 
I took the rudder off and it can be turned perfectly by hand. 
But the same happens with the engine. No power for a few seconds, all instruments off, no rotation of the motor. 
Does anyone know this problem. 
Does anyone know how I can find out if it's the motor or maybe a relay that doesn't work. 
Can I test the motor without a relay, maybe on the 4 cables marked D1, D2, and A1, A2?
I am grateful for a quick answer.
