Not saying it will cause instant death or the world to end... just that yamaha specifically says NOT to do it even though many do and have no issues.

Interesting. I have never run it for long but when I start up in the Spring I run it for a couple of minutes. Of course, I change the entire water pump assembly including the impeller every year so maybe that's why I have never had a problem.
