Whaaaaaat????



I can't imagine what that must have looked/sounded/smelled like. That has to be a $50K "oops."

Sounds like a case of someone w/ more money than sense.

Yep it was a lawyer's first boat. He picked it up from an estate he managed, for pretty cheap. The kicker was that the engines were just majored a few months before this happend. So he had to pay twice.


Cost him $70k to fix.

It's not all that uncommon on the Detroits. When the governor malfunctions, the rack goes to full open. The captain must realize the situation and keep the engine in gear.........even if it means heading back out to sea.......until he can get it properly shutdown.

One of my 6-71's did the same thing...........went to full rack with massive smoke. It did respond to the fuel shutdown solenoid and I didn't have to resort to an engine room run. But, the engine temperature climbs dramatically during such an event and there's not all that much time to get it shutdown before it overheats.

Docking it with one engine was a bit of a trick.

Brian where is that ferry out of? I know I have seen it before, but I can't place it.

Anyway, he didn't know what to do, and started to panic. Large boat, getting close to the beach quickly a 30+ knots, throw in a captian with no experiance... What he should have done was turn it around, throttle the starbord right down and called up the mechanic on his cell. The boat only had a couple hundred gallons worth of fuel on board. Worst case he could have just ran it between CT and NY for an hour or two until the fuel ran out. I forget exactly what broke, my dads friend ended up doing all the work, before and after so he knows all the details.

That's the charter boat.........not the ferry. It's out of Bay Shore, NY.

Yep........they all panic.........and they pull them out of gear. Goodbye engine.

Put the starbord in reverse and pivot quickly (shaking like hell).......then hook up and head out until you decide how to shut it down.

Now, if the engine blows like that on a boat, could it damage the boat enough to sink it?

It doesn't "explode". It melts a piston or seizes a ring and just shuts down. It might throw a rod through the block in a rare occurrence. The boat is never in any danger..........just the wallet of the owner.

I experienced a runaway diesel first hand in a 79 Peugeot 504D normally aspirated. I was driving and all of a sudden the car started accelerating full throttle. I didn't know what was happening and was scared *****less. I turned the key off, it kept accelerating. I stepped on the brakes to slow and was able to stall the engine. I was new to diesels at the time and did not know what the cause was. Got towed to the dealer which revealed the IP had a leaky seal which filled the crankcase and ran away when it reached the right level. I have never seen the dipstick that high.
