my hour meter is the same with almost the same hours. I think its 660 hours 10 min and 22 seconds.

Thank you for the reply but what happens when its say 800 Hrs? I still don't understand the concept of what each hand represents.

I think when it says 600 hrs ,your engines need to be rebuilt ,and the meter start all over again ... haha not trying to be a smart ass , I never saw a gauge like that ,must be one piece of engineering back then.

Best guess smallest plus middle plus largest. As each revolution of largest is 1 hour moves next hand in 1 hour. I say it's 670 if it has rolled over once. If not its 70 and largest hand would represent minutes or the decimal on a reg hour meter.

I think it says 672 hours and 22 min. Each hand counts 60. Big hand minutes, middle hand 60 hours. small hand counts multiples of 60 hours.

On mine the Biggest hand moves every second when my engine is running. Then the next one is minutes, then the small one is hours.

I had one on mine until it stopped working last year (took it out and put in an updated depth finder), I couldnt figure it out either
