Winding up an old diesel

[pugwash]

Not a trick question but related to a rescue incident in Norway last month. Imagine you're running a 60-year-old harbour ferry when a Mayday is heard out in the sound. As you head for the scene the engineer disappears into the engineroom with a screwdriver and suddenly the old ship's normal 10 knots has been cranked up to 13.5. When I asked the engineer what he did to increase speed he just winked and put a finger on the side of his nose. I'm really intrigued. What exactly might he have done with his screwdriver to make such a startling difference ?

Removed the throttle stop?

Or opened up the governor, but the throttle stop thing is more likely. Many moons ago we used to do that on the company vans. Never thought you could get a Talbot Express to hit the magic ton then creep passed it.

We regularly used to back the throttle stop out on our RN chevertons, they had 6354s in them and they would move along quite nicely that way, incedentally the engines were smoother as well.............keith
