An induced flow underwater vehicle motor cooling jacket adaptable to an underwater vehicle motor is provided. The cooling jacket has a self-priming inlet incorporated into the afterbody motor shell section which ingests seawater during either vehicle movement through the water or operation of the vehicle motor. The motor cooling jacket has a coiled tubing assembly, forming a heat exchanger with a variable tube cross-section, wrapped tightly around the motor. One end of the tubing is attached to the self-priming inlet and the coolant discharge nozzle at the opposite end of the tubing exhausts to the region immediately ahead of the vehicle propeller. Solder is applied between each coil to maintain strength and the tightly wrapped configuration of the cooling jacket.
