We are in the engine room of an old tug built in 1960 by Blount Marine, where we see the full blow down and start-up of the Roots Blown EMD 16-645E3 engine. Enjoy the view as the engineer opens up all of the air valve cocks and blows the engine down to clear it of any moisture, then closes them up and starts the engine up. After the engine is started, listen to the engine as it revs a bit, after giving a bit of pressure to the lay shaft. If you have any questions about the video, feel free to message me. Comments are welcome. The video was taken on January 13th, 2017
