How to check engine hours through ECM? 1999-2002 Mercruiser EFI

[tige4life]

I am in the market for a Tige 21V/23V am want to compare the hour meter on the dash to how many hours are on the motor? Is there a specific diagnostic tool that I need for this? What would I need to do this when I go look at a boat?

Thanks,
Logan
