Product Overview
Restore your compatible pool pump with the Hayward SPX1605Z1M 3/4 HP MaxRate Replacement Motor. This genuine Hayward motor is designed for supported single-speed pump configurations, offering a practical repair option when the original motor fails but the pump housing and hydraulic components remain in good condition.
Featuring a 56J frame, C-face mounting, and threaded shaft, the SPX1605Z1M connects to compatible Hayward pump assemblies. Its 115/230V dual-voltage capability allows installation on either supported electrical supply when correctly configured according to the motor nameplate and wiring diagram.
This motor is used in select Super Pump®, Max-Flo®, and Super II® applications that specify the correct 3/4 HP MaxRate motor. Replacing the motor can preserve a serviceable pump assembly and its existing plumbing connections.
Important Purchase Notice: This listing is for the replacement motor only. The complete pump, impeller, seal plate, shaft seal, and plumbing components are not included. Confirm the original motor’s horsepower, service factor, voltage, frame, and shaft configuration before ordering.

Pump-family names alone do not establish fitment. Match the replacement to the exact pump model, motor specifications, and installed impeller.
Do not substitute this 3/4 HP motor for a higher-capacity motor based only on matching mounting dimensions. Compare horsepower and service factor to confirm that the replacement can support the pump’s load.
Installation and Replacement Guidance
Installation should be completed by a qualified pool professional or electrician. Disconnect power before service, configure the motor for the available voltage, and maintain proper grounding and bonding.
Replace the mechanical shaft seal during motor replacement and inspect the impeller, diffuser, seal plate, and accessible gaskets. Order the seal according to the pump model rather than the motor number alone.
After installation, verify priming, leak-free operation, and normal motor performance. A new motor will not correct a blocked impeller, damaged pump housing, or electrical supply problem.
Frequently Asked Questions
Is this a complete pool pump?
No. SPX1605Z1M is the replacement motor only.
Can it run on 115V or 230V?
Yes. The installer must configure the motor for the available supply using the supplied wiring diagram.
Is this a variable-speed motor?
No. It is a single-speed motor.
Will it fit every 3/4 HP Hayward pump?
No. Frame, shaft, voltage, service factor, and pump configuration must also match.
Should I replace the shaft seal?
Yes. A new, correctly matched shaft seal is recommended to help prevent leaks from damaging the replacement motor.
