Cool

It is difficult to know just what you want help with, you never went back to items you mentioned, just really hard to follow what you want.

First, all the power in a boat is in the packs, not in the motor or the ESC. Better quality packs mean better performance and longer life. The reality with boats like this is that the average user probably only runs it ten to twenty times then puts it in the garage. So the makers only build the boat with a limited expected life to kerp the cost down. Without knowing the exact packs you are using, I would guess they are low-end with limited power and life. If one pack swelled then it is bad, and it could have been responsible for the ESC failure.

Heat is the enemy of electronics, and running the boat until the LVC kicks in may mean the motor, ESC and/or packs were overheated, especially in Summer months when the water is warm. This will shorten their life and may cause performance degradation.

But you mentioned water in the boat. Water and electronics do not mix, and water in the ESC will eventually ruin it regardless of any “waterproof” claims. The only way to keep water from entering through the hatch is to carefully apply hatch tape. Water can also enter through the stuffing tube or any hole through the hull.

We do not know what “metal” prop you used, but most must be sharpened and balanced before use. Otherwise performance will be degraded and you may damage the strut. Was it a prop recommended by Traxxas? If not it could have put an excessive load on the motor and overheated everything......

Buy a cheap IR gun and check the temps of the motor endbell, the DSC and the packs after a run. If any are over 140*F then younwill need to reduce your run time or use a smaller prop. Oh, and running at part throttle can be very hard on the SSC and is a major cause of ESC failure.

As you can see, lots of possible causes for the pack and ESC failures. But all can be corrected with a little knowledge. I haven’t seen one run, but that looks like a great boat!
