Maybe. But it would be good to know WHY there's a time limit as well as an hour limit. There are things in a C/S propeller that (especially if not used much) that can deteriorate with time (O-rings, etc.). Failures of these things might be relatively benign, or they might not. At least you should know what the consequences of ignoring the lifetime limit would be. Maybe you can just run the thing until it slowly starts to not work - maybe not... I'd at least ask McCauley so that you can make an informed decision one way or the other.
