Running on oil..... and there's quite a bit in there. Guess they don't have an air shutoff?

Fortunately it seized up. At least it wasn't running backwards.

Damn, that's impressive, but not in a good way.

Re mime to check my air shutters

Having worked around diesel engines my whole life and seeing two run-aways the first thing I checked when we purchased Lightfoot was the operation of the blower dampers on the 671's both worked fine, shutting off the air is about the only way to stop a run-away

Did any of you watch the video of the runaway 453 that followed that one? LOL

A broker we met told me the story about his boat. He's up in Ct and winters in Fla. Had a beautiful 42 bertram with 6-92's for 14+ years. Would bring the boat to fla when he went down. Had the engines done in Fla, but after the rebuild they couldn't get them to rated rpm. So he goes back to Ct while they're trying to trouble shoot the engines, Gets a phone call from a boat tow company, asking are about him and the boat. He says i'm in Ct, what are you talking about? They send him a link, and he see's his boat burning to the water line in real time down in fla. Mech's were trying to get them to rated rpm and one ran away and couldn't shut it down. too bad, was a beautiful boat.

I only hear about DD's sometimes running away. Is it a 2 stroke issue, a dd design issue, or can it happen to any diesel? Still love a 2 stroke dd tho

It can happen to any brand, but tends to favor turbo charged engines.

A friend melted a turbo bearing on his QSM-11. Quite the show. Blew/burned 7 gallons of oil out the exhaust in about 2 minutes. He was behind us and we couldn't stop as we were passing under a bridged that had opened for us. He was a ways back and we had no idea what was going on. Called CG on the radio. CG did not know what a runaway was (I knew at this time what was happening).

He saved the block but had to change a lot of parts including crank to rebuild. No fire. Just stopped when it ran out of "fuel".

Pulling the handles to check this weekend. And maybe a few drops of lube on the hinges.

I had a "tiny" runaway on a 692. Started the engines just to warm them up and port RPM's kept going up. Got it shut down and contacted a wrench who diagnosed a "hung" injector. Replaced ( inexpensive) and all was well.
Actually...used this forum to track down the DD mechanic I used anx when he got into the engine room, he said; " I did the re-build on these engines!"

I experienced our generator running backwards after doing the impellers. Nothing like a ton of soot in your face. It shut down on it's own after about 10 or 15 seconds.
