Stevo....

Did you get lucky??? Fire her yet??? Running and no noises that make men cry???

If not and it were me... I would sit in the thinking position (rubbing chin) and ponder all things that could be affected by the runaway AND excessive vibration... Mounts, brackets, impeller, etc... easy stuff to check...

I always had one except once, and I never want to hear a 6V53 scream like that again guys were dropping tools and running.
Never use your hand or any other body parts. Rags will be sucked in. Even a rubber flip flop has a pretty good chance of being eaten. A leather soled shoe might stop it. Just need to cut off the air to the intake. Diesel can't run without air.

Re: Engine at all oil and over revved like mad!!

This happened last June on the way to Bermuda from the BVI's, there was no damage to the engine, other than a leaky injector seat, the main things were to shut off fuel, at stop cock, the fuel cut off on deck would not work and to use thick wood, metal pot/frying pan or the like over air intake, im sure a c02 fire extinguisher would have worked very well or one of those halon engine bay ones would also have done the trick, powder would have done too much damage.

Glad to hear all is well Steve.... This thread has inspired me to step up my (almost) mediocre maintenance schedule ...

Re: Engine at all oil and over revved like mad!!

I have a dumb question. The few small boats I've sailed had a manually operated butterfly that is used to normally stop the engine by cutting off the air. Is this not sufficient to stop the engine under these kinds of circumstances? Should I still keep something handy to block the air inlet if something like this happens?
Thx.

Gary

Yes & Yes. As noted above, a properly size throttle body or even a large enough ball valve. Just don't restrict the normal air flow. You can probably find everything needed here. I use a 3" and 1-1/2 on my wet exhaust as through hull shut offs. (Engine & Gen).

Ball Valves, Nozzle Valves & Check Valves

They will custom mix the end connections so I have BSP to hose barb
