Saw a couple of Detroit 671s yesterday
« on: May 31, 2012, 02:44:11 AM »
Nothing particularly unusual in that, just the first time I have personally seen any Detroit Diesel engines here. They were in a 1960s ex-Naval patrol boat thingy which is now on the River Thames, and which a friend of mine is converting into a pleasure cruiser for it's owner.

Minimal soundproofing, and the engines were bolted straight down onto the wooden beams of the boat's hull. I guess the Navy considered that using rubber engine mounts would be altogether too decadent and pretentious. I didn't hear the engines run, but apparently they do regularly and have a prodigious amount of power, far too much for the Thames

Same as with captured spies, we'll trade back one Bedford for each Detroit.  :D

My next door neighbor was the head riverboat mechanic for his base in Nam.  Those patrol boats usually had 90's in them and didn't last long between rebuilds.  They could probably have the injectors changed and be dialed back a bit.

Marine engines can indeed have prodigious power, since they have the whole ocean to keep them cool...

My good ole USN used these engines by the thousands, called them Gray Marine engines, in all sizes and shapes of boats.
