My 1998 Mercruiser 5.7 tbi refi boat has a strange issue. The tach (vdo) shows rpm's but the hour meter is not working/advancing.
Any ideas?

Ayuh,.... Sounds like an internal gauge issue,...

Another tach is probably the answer,....

Probably is the gauge, but check the connections on the back

AllDodge, you are right. Checked connections, tighten everything now works fine.

Cool, just think all the hours that would have shown up, now you have a lower hour boat :rolleyes:
