This page is the 2021 South Seas Spas reference library: the factory owner’s manual as a free PDF you can read right here or download, plus the 2021 parts side of the story — because where a factory parts book has pages of parts, our site has pages of parts you can actually order.
2021 South Seas Spas Owner’s Manual (Free PDF)
South Seas Spas did not issue a separate owner’s manual for the 2021 model year. The factory document that applies to 2021 models is the October 2020 Gecko-control manual, shown below exactly as it was issued. We have not renamed it or restamped it with a 2021 cover — it is the genuine document, and this is the year it covers.

2021 South Seas Spas Parts
The factory parts book for 2021 is a dealer document and stays that way. What we publish instead is the useful half of it: the parts documented for South Seas Spas models, each on its own page with the OEM part number, a photo, a price and fitment help.
South Seas moved from Balboa to Gecko control systems during 2020, so the control system on your spa — not just the model year — decides which manual and which control parts apply.
