I replaced all my gauges this year..........

When I started the engine for the 1st time last w/e the voltage looked a little high so I measured it...........~14.2V @ the batteries.

I am thinking this is ok.............just looked differetnt on the new gauge.

Re: Charging Voltage

Tony, per the Merc Manual...​

1. Ensure battery is fully charged by using the hydrometer test outlined in 4A.
2. Start engine and increase RPM to approximately 1500 rpm.
3. Check voltage reading. The voltage should read between 13.8 and 14.2 volts. If the reading is below 13.8 volts:​

Sounds like everything is good.​

Re: Charging Voltage

Yep,14.2 is great....you will notice after it runs for a while it may drop in the 13 volt range. Its topping off the charge....;)
