My boat is a 2006 carver 41 CMY with twin gas Volvo’s. Both hour meters sometime ago quit displaying fully. So an 8 might look like a 6 or a 9. Checked with shop and they said they could read actual engine hours plugging into the motors diagnostics, so didn’t worry about it. Now, port side is close to readable, but starboard side does not display enough to read. Port side has the blinking h to the left of the hour meter when engine is running, but starboard full display just blinks whatever is left still working. Basically unreadable. is a fully blinking hour meter a warning of some kind? Oil, temp, and volatile all read good on both engines.

I can’t find a manual on the guages and Hour meter display anywhere.

Thanks!
