Kyosho B0108-21 38mm Water Jacket for RC Surfer 3 - Performance Cooling  [KY-B0108-21]

Designed Cooling for Water Running

The Kyosho B0108-21 Water Jacket 38mm provides a practical method to manage motor heat on the RC Surfer 3 by routing cooling water around the motor body. The 38mm internal diameter is matched to the intended motor size for a neat installation.

Advantages for Water Use

Persistent high load in aquatic environments can push motor temps up. This water jacket gives a direct path for heat transfer to the surrounding water, helping to reduce thermal strain and maintain steady throttle response.

Installation and Upkeep

Push the jacket into position so it seats evenly on the motor and verify all seals and fittings. Remove salt, grit, and residue after sessions to avoid blockage and corrosion risks.
