* Merc 5.0 EFI with Alpha Drive about 50hrs on it <br />* Winterized by Merc Authorized Mechanic in Nov 2003<br />* Memorial Day weekend...started for the first time, did not see the water pumping out of the back left (from the front of the engine) side of block.<br />* Ran engine for about 10mins, up to plane @4200rpm, before we noticed the issue.<br />* Shut down and towed back<br />* About a week later (due to work/schedule conflicts) Mechanic came to the boat from dealer, put plug in.<br />* I was not there, but my father was, when the mechanic started the engine it was missing, and as my father described it "hissing".<br />* My father checked the oil and it is still fresh and clean (no water as far as we can tell ).<br /><br />It is going into the shop on a trailer today. <br /><br />What damage could we have done? <br /><br />My guess is the head gasket is blown between the cylinders that are missing.<br /><br />Does the 2000 Merc 5.0 EFI have aluminum heads? Could a head be cracked?<br /><br />What else could it be? Fouled plugs from the fogger?<br /><br />The dealer is already saying "we don't know what happened to the boat between Nov and now... we would not have left that drain plug out." etc etc. So I am trying to get a quick education before they start work on the engine tomorrow... any input would be welcome.<br /><br />Thank you in advance
