Engine stops

During our Westbrook, CT to Croton, NY trip after the storm the engine died. It just shut off after the cabin filled with smoke.

I found that the exhaust hose after the raw water input Y had fallen off.
I reattached it and the engine seemed to work fine.

I was thinking at first that the engine needed the back pressure but Caleb suggested that because exhaust was filling the engine room it did not get enough fresh air for combustion.

This seems more likely to me but is that all their is to it?

Any damage that could result from this incident?

20 years ago, my dad had a little honda outboard that was acting up. It would lose power and eventually quit. We had eliminated the fuel and spark legs of the combustion problem, that left air. He had a small leak in his exhaust. The engine needs 02 to burn. C02 will put fires out, even combustion fires inside your cylinder. Good call on Caleb's part. I wouldn't expect any damage at all to the engine, just a little soot in the engine compartment.

Engines like people have to breath. The exhaust fumes that filled the area where the engine is are no good for an engine to run on so it stopped. Also if the hose came off it is possible that the engine temp may have gone up and it is possible that there may be a temp cut-out device fitted.

But I lean towards the engine running out of usable air

i expect that exhaust water/steam [which would have surely filled the engine compartment]got sucked into the intake and caused the engine to die,i doubt there will be any permanent damage.about the same thing happened to me 3 yrs ago

This actually sounds the most likely.
