I'll build on this. Did you have an audible oil pressure alarm or just a gauge or light? Is it possible your oil pump failed and you didn't know it? Did you hear any knocking when you started it or hear pinging from oil-starved lifters?
 
That's the messed up thing about it, it had 125 hours total, no warning and I am always keeping my eyes on the gauges, the temp, oil presure everything, I used the West Marine recommended oil and filter last October. I though it was a bit odd that it was taking so long to get up on plane, I only had about 450lbs of people on a boat that states 1200lbs. I noticed one thing though, when I tapped the shallow spot prior to the engine failure that caused the engine to stall the deck rails seemed to vibrate more at a certain idle speed so I stopped the boat and checked the prop, it had damage but it looked rather mild, some sharp edges was about all.
 
There you go, you may of knocked engine out of alignment.
That could very quickly destroy the motor.
When every you run aground alignment should be checked.
Remember you have 2 devices that are fitted together and need to be precise.
They have an alignment tool they use for I/O's.
 
So, it turned out to be a connecting rod shoved itself into my oil pan. Nobody knows why a motor with 134 hours on it does this, maybe years of sitting idle, who knows, now I have a new expensive motor, 300 hp where it was 220. I got this boat at a bargin and now its pretty much a wash. Thanks all for your input!
