Bilge pump run time clock

[Lake-Effect]

Someone handy with an Arduino or other microcontroller could whip up a simple bilge-pump logger.

You might even consider an inexpensive boat monitoring system like FloatHub, which I believe will sense and record any desired event like bilge-pump runs. It of course also monitors many other things like battery voltage, etc etc, visible at any time from a website, and it can send emails or texts for selected alert conditions.

I have no connection or interest, except that I was working on a similar system... til I found out that they were a couple of years ahead of me . I really like what they did.
