It all depends on the nut behind the wheel. Not the nut behind the prop "wheel" but the guy behind the steering wheel. Same lower end engine. So yeah the 210/215 version just ensures no one pushes things too far, too long, too much. But it is a pretty robust engine. Tony says its not a limit of hours rather a limit of how many gallons you get to put through one of these engines, the 370 just lets you put those gallons through faster.
