I was "told" that the 8.1 Vortec is the only marine engine that 100% passed the Mercruiser "dock test". I guess they run them wide open throttle for x amount of hours. Someone else may chime in with more knowledge.

Should I buy it with the 8.1

larry said that also .
See bottom of this link:

Or this is copy/pasted from there:
"Because about 25% of GM's larger engines are typically sold for marine use, much of the testing on the Vortec 8100 was done using the marine market's more severe-duty parameters. In one particular test, called the "Marine Dock," an engine is run at virtually wide-open throttle for 300 hours straight (60-minute cycle—55 minutes wide-open-throttle/5 minutes idle)."
I'm not sure if its still the only motor to pass the test, but I think back when the very first did the test on the 8.1, at the time it was the only one to pass, I can't confirm that though
