Description
Beginning November 2024, the manufacturer has introduced a design modification with an off-center capacitor placement that may impact certain installations. To guarantee proper fitment, Global now ships this as a separate 10.5 Amp motor paired with an authentic 2.5 HP XP2 wet end for on-site assembly. Assembly is straightforward, and our team is available to provide guidance if needed. This approach ensures you receive components that work correctly the first time. We anticipate the original configuration may return in future production runs. If the revised capacitor positioning works for your setup and you have adequate clearance, contact us to request the pre-assembled version.
Independent Supplier & Replacement Part Notice
We are an independent parts supplier and are not affiliated with, sponsored by, or endorsed by Watkins, Hot Spring, Caldera, Tiger River, or Solana. These names and their part numbers are used only to identify compatibility.
We offer replacement parts as alternatives to spa-branded parts. When this listing identifies a part as the same original-manufacturer replacement, it is supplied under the component manufacturer’s branding and part number, which may differ from the Watkins or spa-brand label and number. Other compatible alternatives are identified in the individual product listing. Please review the listed specifications, fitment details, and any installation differences before ordering.
This is the Watkins 39578 Vendor Code 4081 replacement featuring a 48-frame 230V dual-speed motor with 2" x 2" wet end connections measuring approximately 3" across the threaded unions. Electrical requirements are 10.7 Amps at high speed and 3.2 Amps at low speed. Functions as either single-speed or dual-speed configuration.

Pump Bleeder Barb, Watkins, Wavemaster, LX, 1/2" Barb x 1/4"Mpt
Important Information Regarding Watkins Wavemaster Pump Assemblies: Watkins sources pumps from various manufacturers and applies their part numbering system. Global supplies the actual factory pump or nearest current equivalent that matches your original specifications, sourced directly from OEM manufacturers. Our units do not include Watkins proprietary branding. The primary distinction is that our pumps feature standard motor ventilation rather than the rear exhaust vent modification. We believe conventional motor cooling design provides superior performance and longevity for end users.
