Can you check your charger to see how many amps it is.....maybe there is a plate with the makers name and some specs.......it will tell you what you can replace it with without too much drama. Pronautic seem to be ok, for us anyway.

Re: Connected to shore power, gauges look good, but no power
That might be different with the new charger you buy. Many new chargers have dedicated outputs, say a 20 Amp two bank charger has two 10 Amp outputs. If you only use one then you really only can get 10 Amps (so if you have just one bank they recommend you connect BOTH charger outputs to that bank, so you get the full 20 Amps).
With a boat your size, I would go no smaller than a 30 amp, and I would probably recommend a 40 or even larger, but it depends on how much D.C stuff you will be running on board. You also need to verify the wire sizes if you go larger, but since your "charger" breakers on the panel were 40 Amps, then the wiring should support up to 40 Amps per battery (so, on some two-bank chargers that might bet two 40 Amp outputs, or an 80 Amp charger... that might be overkilll though)

That being said you can change wiring to go bigger if you feel it is necessary. In my case I am installing an 80a charger. This requires I replace the 15a breaker with a 20a, replace the wire from the breaker with 12gauge and increase the wire size from the charger to the battery.

Re: Connected to shore power, gauges look good, but no power
- if it's being mounted in an engine compartment, ensure it's ignition proof
- look for a "marine"charger
- make sure it meets all North American safety standards
- judging by your current unit, ensure you get a 12 volt charger
- unless you want to replace your wiring, the charger's output to each bank can't exceed the limits of your current wiring/circuits. Don't just go by the breakers you currently have. While they are likely rated for the size of wire you have, the new charger may require a certain breaker rating above its rated output per bank, some require breakers 5 amps over their rated output while others require breakers 10 amps over their rated output to each bank, this is important for safety and to avoid nuisance tripping
- take note of the required input. It's likely your current circuit is 15A, 60 Hz (North America), 14/3 wire
- in general, the size of your battery banks, primarily your house bank, and the type of boating you do has an impact on the size (output) of charger you should get
- your charger's performance is only as good as the condition of your batteries, and your connections so ensure they are good quality coated connectors, and that they're clean and tight, use shrink connectors and shrink tubing
ProMariner ProNauticP series chargers are a good choice, I've installed many. If you're handy with tools, we can walk you through the installation.
