In board built motor connector

Hi,
I want to integrate the connector between the mast and the board.
This seems a good and nice solution, but:
What would be, if I crack the mast from the board?
This will happen under load, detach the connector and the bare connection would be in the water.

I ask this, because this happened with me once, but I had a long wired connection between board (esc) and mast (motor) that time.
