Marine Cooling Solution for Surfer 3

The Kyosho B0108-21 Water Jacket 38mm is crafted to assist thermal management on the RC Surfer 3 by guiding water around the motor casing to carry away heat. Its 38mm sizing matches the intended motor envelope for straightforward fitment.

How the Water Jacket Helps

When running on water, continuous load can raise motor temperatures. This water jacket provides a direct route for heat transfer to the surrounding water, helping reduce the chance of thermal cutoff and sustaining performance in marine conditions.

Fitting and Care Advice

Fit the sleeve so it makes even contact with the motor surface and check any O-rings or seals during assembly. Periodic cleaning and inspection will prolong service life and keep cooling consistent.
