Grady White Freedom 235 2021 have had a problem with battery drain on starboard battery when battery switch is off. Bilge pump and yellow entertainment radio cable to maintain presets were hot wired. I had radio preset cable moved to the battery switch (no longer hot wired). Still seem to have a drain problem when switch is off. Highly doubt it is the bilge pump. Recently discovered a breaker I'm told sparked when battery cable was attached to the battery (switch was off). This device is mounted right under the bottom of the hatch opening that accesses the batteries. Was told this might be "Clean Power" to the Yamaha motor. Because of this he was reluctant to switch off the breaker. With minor research, I believe Grady White does not use a clean power connection but rather through a standard battery switched harnas. Is any one familiar with this device and know what it is? What is connected to it?
 
It's hard to follow what you're saying... can you better describe things -- or post pictures?

Is the battery healthy? Have you charged it and load tested it? That's the first step. You could also do an amp draw test - depending on results, then figure out what is drawing excess power.

I’ve replaced the battery 3 times. A brand new battery was recently installed. I was informed by a Grady dealer the battery before that was the problem and that battery was replaced and was told problem solved. Over a period of the boat not being used I discovered that battery was completely discharged. Brought it back to the Grady dealer. After spending a few days with the boat, the dealer informed me that Grady has discovered the directly connected wire from the radio that maintains the presets in the cause of the problem and they recommend putting that wire on the switched circuit.
My boat is kept on a mooring with no access to AC power to charge. I was told that with 2 x AGM batteries, a proper mix of usage of the 2 batteries and lengthy runs the alternator should maintain the batteries.
I recently found that #1 battery completely discharged. I assumed having previously been completely discharged it was compromised. I bought a new battery, and had a mechanic install it. The damaged battery was tested and determined to be damaged.
While he was installing the new battery as previously mentioned he noticed a spark at the breaker device mentioned. It leads me to believe there is still something perhaps that breaker that is drawing on that battery when the battery switch is off.
In all this time I’ve never had a problem with the #2 battery.
At this point I’m trying to determine what that breaker is for to determine if it is the cause of the draw.
 
When something sparks when power is connected, it simply means it's a "live" circuit - that's not a good or a bad thing... just a "thing".

We'll need more info or pictures and/or wiring of whatever breaker this is you're talking about.

Is this a Fusion stereo? I've read recently about some of the higher end ones pulling a rediculous amount of amperage when only in off/standby mode. On a recent post in a Sea Ray forum (Fusion stereo), it was found that the standby power was using a 20a fuse! That's absolutely rediculous if it's true.

It's easy enough to figure out the draw by doing what I mentioned above. But maybe this is what your dealer has already done - or will do.
