Please. Be careful with the sand. Keep those electrical connections clean…

At this stage you’d be best finding someone that can repair this for you.
It’s kind of evident you need the extra support merely by the suggestions you are making like cutting into the board instead of just cutting the cables and leaving the potted mess at the bottom.
Its also evident from the amount of sand you are getting into the seals that your boards is most likely letting water in all over the place. Sand is every seals enemy.

you are right. 
this post is published with the purpose that someone who understands this in south florida will be found. but for some reason it seems that on this forum I am the only one from south florida
Here’s my take:
- You clearly need some new o-rings for the plugs.
- There seems to be corrosion in your receiver, although the Transmitter says its connecting. You’ll need to confirm if its just dirt or corrosion?
- The motor continuing to beep can be 2 things. Either the receiver is not functioning correctly and as a result the ESC cant calibrate. Or the ESC is seeing a voltage it thinks is too high and wont start up correctly.
The problem is that to try fix the issues, you need to connect another receiver which is a bit tricky considering they potted all the connections to the existing one. To reprogram that ESC you also need to access the very same connections…
Be careful using chatGTP, I know Zedman really likes it but it can lead you down a lot of different paths which can be confusing as it is only an AI that scraps info from different places on the internet. It is good at explaining what certain nomenclature means and describing what different things are. I use it all the time but have to sift thru what info it gives me to get the answer I am looking for to the problem I am inquiring about.
ChatGpt is like a PhD graduate who has never actually done anything practical in its life with terrible tunnel vision on any question you ask.

Version 5 is as if the PhD graduate is drunk and high after graduation.
But still a PhD graduate.

That’s all we’ve come to. It still isn’t clear how to check what exactly is malfunctioning
I agree this is most likely the same Maytech ESC. I use it for my 40v foil assist. It works very well as long as it gets plenty of water to remain cool. The motor beeps when it loses connection with controller and when it has an error like low voltage or high heat that puts it into limp mode or dead mode (depending on how it was programed). As noted in the Maytech ad above, it’s programed by hardwire to a small programmer. The ESC does an auto-reset of the limp mode (dead mode) when completely disconnected from the battery. If the motor continues to beep when the controller is on, the controller is not connecting to the receiver. But the motor/ESC is getting power from the battery. I agree with the summary above that it’s probably your receiver. I use a Maytech, so I have no insight into yours (I’m not sure what it is.) Obviously, this is not a quick fix or the manufacture would have helped you. If you enjoy working on things and learning new things, dive in and get your hands dirty. But be safe! And be prepared to make mistakes that may cost you more money. Education is not free. I paid my tuition during my first assist project.
