Why the B2983 for a Hayward TriStar?
Replaces the Discontinued Motor
The original Hayward SPX3210Z2MER is discontinued. The Century B2983 provides the same dual-speed operating format for compatible TriStar installations.
Same Motor Frame Style
The B2983 uses a 56Y square-flange configuration with a threaded shaft, making it suitable for compatible TriStar wet ends designed around this motor style.
Two-Speed Operation
Run at 1725 RPM for lower-speed filtration and switch to 3450 RPM when greater circulation is required.
Keep Your Existing Pump Wet End
When the pump housing and hydraulic components are still in good condition, replacing the failed motor can avoid replacing the complete pump assembly.

Frequently Asked Questions
Does the B2983 replace the Hayward SPX3210Z2MER?
Yes. The Century B2983 is a commonly recommended dual-speed replacement for the discontinued Hayward SPX3210Z2MER / SP3210Z2ME used on compatible Hayward TriStar pumps.
Is the Century B2983 a two-speed motor?
Yes. The B2983 operates at approximately 3450 RPM on high speed and 1725 RPM on low speed.
Is the B2983 208V or 230V?
The B2983 is rated for 230V. This is important when replacing an SPX3210Z2MER because the original Hayward motor was labeled 208–230V. Verify the actual supply voltage before installation.
Does the B2983 include a Hi/Lo switch?
No. The motor is supplied without a manual Hi/Lo switch. If the pump is controlled by an external two-speed timer, relay or automation system, a motor-mounted switch may not be required. The commonly used manual switch kit is 2512558-001.
Should I replace the shaft seal when installing a new motor?
Yes, replacing the shaft seal is strongly recommended whenever the motor is removed from the pump. Reusing an old seal can allow water to leak back toward the new motor. The correct seal or tune-up kit depends on the pump wet end, not the B2983 motor itself.
Will the B2983 fit every Hayward pool pump?
No. Motor compatibility depends on the pump wet end, motor frame, horsepower requirement, voltage and shaft configuration. The B2983 is commonly used with compatible Hayward TriStar applications but should not be assumed to fit every Hayward pump.
Installation Note
Always replace or inspect the pump shaft seal when installing a new motor. Verify the pump wet-end model, incoming voltage and two-speed wiring before installation. Electrical work should be performed with power disconnected and in accordance with the motor wiring diagram and applicable electrical codes.
Replacing an SPX3210Z2MER?
Send Aqua Terra Backyard a clear photo of your existing motor label and pump housing. We can help confirm whether the Century B2983 is the correct replacement and identify the shaft seal or pump tune-up kit needed for installation.
