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 complete service kit is designed for Watkins hot tub pumps, specifically Vendor #04184, known as the Wavemaster 3000 model. The kit includes (1) shaft seal with installation tool, (2) bearings, and (1) 1/2 oz tube of The Professor's Silly Juice - a premium silicon sealer specially formulated for spa applications.
Important: Watkins utilized 4 different wet end manufacturers under the Wavemaster designation. Verify your pump label shows 04184 before ordering.
The seal assembly consists of a spring seal component that mounts on the impeller shaft and a ceramic/rubber component that installs in the volute housing. Both seal parts feature approximately 5/8" center openings. For proper installation, apply silicon sealant to the impeller shaft, add a small amount of The Professor's Silly Juice lubricant, then carefully press the spring seal into position. The rubber seal component benefits from a light silicon coating for easier installation into the volute or wet end housing.
Professional tip: Leaking seals typically indicate impeller replacement is also necessary, as water infiltration into the metal shaft area causes expansion and impeller damage. This seal services FMHP wet ends found on Watkins Hotspring spa systems. Package includes seal components, bearings, and silicon sealant only - additional parts shown are for reference purposes.
