Hour Meter

[Kenccho]

I just bought a Caravelle 187 with a 4.2 Mercuriser. I did a3 hour trip yesterday and was surprised, that the hour meter run to fast. I startet with 545h after the trip i a had 570h.
The meter goes forward approx every 10 minutes.
Anybody has some help for me?
Thank you

The meter goes forward approx every 10 minutes.

My guess is the motor had 54.5 hours and after a 3 hour trip it now has 57.0 hours (3.5hours total)

Is the last digit a different color?
