TMRC Cooling + Power Kit — 3660 1800KV Motor, Pump & Water Lines

The TFL SSS V2 3660 1800KV is the optimal motor for the TMRC V3 Outboard. It's the exact motor we run in our own V3 builds.

Made exclusively for TMRC by TFL. You won't find this motor anywhere else.

The motor's water jacket is included. It comes on the motor, ready to plug your cooling lines into. There's nothing extra to buy.

This kit gives you that motor plus everything you need to water-cool it, in one box. No more hunting Amazon for cooling parts. Every part in this kit is matched to work together.

What's in the box

1. TFL SSS V2 3660 1800KV brushless motor, made exclusively for TMRC and optimal for the TMRC V3 Outboard
2. Motor water jacket, included
3. Water pump, with a plug-in servo lead
4. Silicone cooling line, 39 in (cut to length)
5. Brass water pickups x2, M5 thread (one intake, one outlet)
6. RC on/off switch, so you can turn the pump on and off from your transmitter

How it connects

Water: intake pickup (under the hull) → water pump → motor water jacket → outlet pickup. Use the silicone line between each part.

Power: plug the RC switch into a spare (AUX) channel on your receiver, then plug the pump into the switch. Flip that channel on your radio to start and stop the pump.

Tip: run the outlet out the transom so you can see the water flowing.
