We happened upon a close-out sale at our local "Gander Mountain" outdoor store. That chain is affiliated with "Overton's" marine supply, so low and behold, they had a complete stock of Sierra boat gauges available at 80% off. So I picked out a whole set of gauges (except for an EGT) including a brand new hour meter. Of course, I could have just mounted it with it reading zero and gone from there, but I thought it would be better to have it showing "real time". So, I rooted around and found a 12vdc power supply from an old laptop and hooked it up.

Here it is after 42 days running, just another 33 days and it will be all set to install in the panel -- long northern Winters have some advantages I guess
