SKU: WK-P500 Category:

The P500 is the most powerful motor we build: 7500 W on a 48 V pack, 8000 W on a 72 V pack, and a stepless throttle that takes you from a slow crawl along a weed line to 30 km/h on open water.

One motor, three battery setups

The P500 accepts anything from 20 V to 72 V, so the same motor works with the pack you already own. It reads the input and gives you what that pack can deliver:

  • 24 V pack – 2200 W, around 1500 rpm at the propeller.
  • 48 V pack – 7500 W, around 3000 rpm. This is the setup most buyers run.
  • 72 V pack – 8000 W, for the last few km/h.

Start on two batteries and add two more when you want more speed. Nothing else on the motor has to change.

Why brushless matters

  • Longer run time – less energy is lost as heat, so more of your battery reaches the propeller.
  • Nothing to wear out – no brushes, no commutator, no mid-season rebuild.
  • Quieter – you hear the water, not the motor.
  • Torque at low speed – which is where trolling actually happens.
