UH OH! Did we hose the engine?

We've got a 2008 CC 206 with a PCM EX 343. Husband's boat-(I'm the cheap good looking mechanic) Anyway, to make a long story short, he winterized the boat last fall, and started it up this spring. BUT, he forgot to open the fresh water valve and drove it for about 10 minutes until the engine went into reduced power mode. He went back to the dock, engine was hot (of course). He is going down this weekend to check it out, to see if any damage was done. Herein lies the question: how do you check for damage in a situation like this-and what tools are necessary-I've ordered the Rinda Techmate scan tool-as that would give us a starting point to look for any freezeframe stored codes, and also any current codes that the engine is throwing. Any other suggestions? Compression test? Impeller involvement? I'm open to suggestions. Oh yes, he will open the fresh water valve this weekend.

The impeller is toast. Start there. Pull hoses fore and aft of the pump because the pieces will go both directions. Back flush until you find most if not all the pieces from what used to be your impeller.
Next concern is the exhaust. Look at the risers, is the paint blistered? Look at the hoses, are they melted? Service as found.
I would probably change the riser gaskets as a precautionary measure.
Check the oil for water, pull the oil fill cap and look for droplets or emulsion. If water is found, forget all the above and go to the nearest bar. Order a double, and another.

Pics needed or course. Not of the boat but of the hot mechanical wife types.

Your fiberglass exhaust down hoses after the manifolds could be a problem, as the other guys said, new impeller, if the old one is missing peices check the hoses for the impeller shrapnel. After that run it and watch everything, temp gauge, hoses for leaks, etc. My guess is you will be OK, limp mode may have saved the day.

I would take everything in this thread to the bank except what was posted by Me, PBrain, Jbear, TimD, Baitkiller & Mark C.....

Ok Boys,
He got the old impeller out-and not too bad, not too bad I don't think, but look for yourselves-next step is replacing it, and then using scan tool. Stand by for more info.

susan the nautique man? when I saw the first post I assumed a mechanic named nautique man with a husband was a gay couple...guess I've been wrong before.

that impeller doesn't look too bad at all...of course, I've never seen one out of the packaging so I have zero point of reference, but at least all the spinny things are still there.

do you have a sister? if so there will be line

Dies it have positraction?

Wrong piece of equipment

To completely diagnose the issue you will need a Hewlett-Packard model 5710a with flame analyzing detectors preferably the floor model since it was turbo-charged!

Glad you ended right side up, but I would still change the oil.

Now let's see some pics of the one and only hot mechanic..

Ok so boat test drive is this afternoon-I feel pretty confident that it's going to go well. Yes, will change oil soon. Nice to see the real sac o suds exist. Yes, will entertain you all in a few weeks with a picture you are dying for, though probably not all that exciting. Has to wait until this leg cast comes off in a few weeks-I do think my virtual fix with my helper onsite worked pretty good this time
