Manuals are a helpful tool for the new owner to discover everything on the boat.
Here is a copy from our SBO archives.
The gauge on the right labeled INDICATOR appears in the manual under the reference "Water Systems".
The gauge on the left was correctly identified by
@Davidasailor26 as a battery monitor. It appears ot be an upgrade from the OEM gauge for the boat. The rough cut of the wood panel beneath the gauge supports this observation. Looking for details on the TR-16 Coulombmeter indicates it is a common Chinese-manufactured unit. You would need to find a seller or distributor to obtain a manual for the gauge. Said coulombmeters are considered unreliable.

- The typical Coulomb counting battery monitor cannot, and does not, track changes in capacity, changes in charge efficiency (though some can) or changes to Peukert.
