He brought it into the shop and they wanted to know how, at first fresh water got into the head. He told them he didn't know what they was talking about, then he was told it was salt water, so when did the boat sink, well the boat never did sink. After back and forth he was then told, "the motor was seized and Etec has a flaw. Here is what the mechanic said the flaw was, Blow off valve nuts and bolts rust causing it to leak salt water into the engine and the pistons were full of water". The motor is being replace with another 200 HP ETEC, a 2012, so if it is true about that flaw, will this motor have the same defect? Now I have a question, only Rh head/block is being replaced, it has 0 hours on it, but they will still be using his lower unit, could that cause a problem, the lower unit is a 19??. I do not know the year of the lower unit.

Since I'm ever the conspiracy nut I always question things. So, since the engine wouldn't go over 3K RPM's my question is how long was it from the time it was running at 3K till when he actually brought it into the shop? It seems fishy (no pun intended) to me that a running engine... even a poorly running engine, was suddenly seized. Also, it's impossible for the cylinders to be full of water since that would cause a hydraulic lock (water does not compress, so as the piston was rising up in the cylinder the water would prevent the piston from moving). The engine would not be able to run. But you said that Lloyd said the engine was running. It cannot be both. Either the engine wasn't running or the cylinders were not full of water. 
In all cases, there does seem to be some problem with the blow off valve nuts being made of steel and the bolts being made of SS on some models of the etec. From the discussion I'll post here it seems the repair is rather straight forward and sometimes quietly covered by BRP. Check out this link. https://www.etecownersgroup.com/post...-Valve-5620499
