HRDCB36WC01 - Aluminum 36mm Water Cooling Jacket - M41

CNC‑machined aluminum cooling jacket designed to enclose a 36 mm in‑runner brushless marine motor. It improves heat transfer and lowers operating temperatures during high‑load running by providing a full water‑buffered chamber around the motor can. Dual water pickup ports increase coolant flow, and precision O‑ring sealing surfaces help prevent leaks while maintaining durability in wet environments.

• 36 mm internal diameter accommodates standard marine brushless motors

• CNC machined aluminum construction enhances heat dissipation and structural strength

• Full water coverage buffer chamber increases cooling efficiency

• Dual water pickup ports allow greater coolant circulation around the motor housing

• O‑ring sealing surfaces reduce the risk of leaks

• Black anodized finish resists corrosion and wear in marine environments

• Direct replacement for rubber water cooling sleeves on compatible motors
