My boat currently does not have an hour meter, but I can retrieve the hours by hooking a laptop up to the engines computer system. I would like to install a hour meter to make it easier to see the hours at any given time, but do they make hour meters that I can add time to so it will match what is actually on each engine?

Thanks in advance

Just connect it to a battery and let it run until you get the number you want, then install in boat
