PLEASE NOTE ON WIRING: we do not know what color wire your spa control uses for high speed and low speed. The photo shows locations indicated by your motor diagram on the label, on the side of your motor, and is for your reference only. We are not suggesting black for high or black for low, this is not determined by the motor, it is designated by your control. If red was high speed for you in the past, it is still the high speed wire now. Some controls use black for high, some brands use red.

If in doubt, call the manufacturer of your control, or use a voltmeter to determine.,

Note, this is a bare motor exactly as shown, no water pump included
