Good point Tony! My engine is a Honda, and it has that feature. The guy that helped renovate my pond had a Mitsubishi engined one that did NOT have that feature. The sand that it was sitting on eroded, and the pump tipped over while it was running. It didn't run for long after that and fixing the oil starved motor would have cost more than buying a new one.
