Been doing some work at the marina again and thought you might get a kick out of these motors... This particular vessel is powered with two, V-12 quad turbo MAN diesel motors. You can see two turbos in-line and there are two more just like it feeding the six cylinders on the other side of the motor. Each produces 1245 horsepower (934 kW). The vessel is a custom power cruiser -aptly named given 2490 (1.87 MW) horsepower is about the power of a locomotive. These motors make the 55' vessel go 50 knots consuming about 50 gallons per hour per motor (100 g/hour) ... Onboard fuel tanks are 700 gallons. Upon getting on board this vessel, it took 20 minutes of looking at the control console to figure-out how to spin-up the motors. There are no mechanical connections from the helm to the motor room -everything is controlled by servos and/or various electronic or hydraulic actuators.
Here's yours truly trying to figure-out what's wrong with the troll gear on the starboard transmission. -And just to give you some perspective, while laying on one motor, I laid my leg on the other. They are surprisingly smooth and not all that loud although ear protection down there is worn while the motors are turning. This is by far one of the nicer engine compartments I've worked in lately. You can actually stand up whereas most are crawl-spaces just barely big enough to get your shoulders through. I've managed to get wedged pretty good more than a few times...
