Hour meter on gauge

[Skin diver]

Does the hour meter on a multifuntion gauge run with just the key switch on and the motor off or only when the engine itself is running?

Clocks time only when the motor is running.

Great. Thanks boscoe

but this lock has no hours run memory after battery disconnected, right?

disconnecting the battery will have no effect on total engine hours.
trip hours are resettable,total hours are permanent.
