An overheating protection device id disclosed for electrically coupling an electrical power source to a fluid propulsion device. The fluid propulsion device includes a propelling member within a manifold for pressurizing a fluid. The propelling member is keyed with a motor. The overheating protection device comprises a housing including a back plate, a top plate, a bottom plate, a first side plate and a second side plate for defining a cavity. The back plate, the top plate, the bottom plate, the first side plate and the second side plate define an aperture. A thermostat switch is positioned within the cavity and is electrically coupled between the electrical power source and the motor. A cover engages the aperture for sealing the thermostat switch within the housing. The cover includes a bore for relieving the thermostat switch. A thermo-conductive layer has an interior surface and an exterior surface. The thermo-conductive layer engages within the bore and the interior surface of the thermo-conductive layer contacts with the thermostat switch for conveying thermo energy between the thermo-conductive layer and the thermostat switch. The exterior surface of the thermo-conductive layer engages the manifold for conveying the thermo energy between the manifold and the thermo-conductive layer. The thermostat switch terminates the electrical power to the motor upon the thermostat switch sensing thermo energy below or above a predetermined temperature range to prevent damage to the fluid propulsion device.
