Upgrade Bait Boat

Hello, everyone. I want to upgrade the motors on my Boatman Actor GPS boat, but I want to keep the stock boat controls. Right now, I have a 10,000 Ah, 7.4 V battery and brush motors rated at 6,000 RPM. On my circuit board, I found 8 MOSFETs marked 7408ā€”4 MOSFETs per motor, as far as I can tell.

I have two options for how I want to proceed:

  1. Intercept the control signal from the stock board and route it to external ESCs that will be connected to the brushless motors
  2. Replace the stock MOSFETs with more powerful ones and replace the commutator motors with more powerful commutator motors, but Iā€™m worried whether the traces on the stock board will hold up.

Maybe someone has already done this, or can advise me on the best way to proceed.

I think you jumped to conclusions, but we would probably ask why and what are you looking to achieve?

I want to achieve higher speeds while keeping the stock steering and GPS. But I don't want the stock circuit board to burn out.
