2018 South Seas Spas Owner's Manual

This page is the 2018 South Seas Spas reference library: the factory owner’s manual as a free PDF you can read right here or download, plus the 2018 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.

2018 South Seas Spas Parts

The factory parts book for 2018 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.

2018 South Seas Spas Manual & Parts Frequently Asked Questions

Yes. South Seas Spas issued a factory owner’s manual that covers the 2018 model year, and it is on this page as a free PDF — embedded above so you can read it without downloading, and downloadable if you would rather keep a copy.

The factory parts book is a dealer document, so we do not republish it. What we do instead is turn it into live parts pages: the parts documented for 2018 carry their OEM part numbers, photos and pricing, and you can order them directly.

Match the part you are removing rather than the year on the cabinet, and for control-system parts check whether your spa has Balboa or Gecko equipment — South Seas changed over during 2020. Send photos and your serial number through the fitment form on any product page and we will confirm the match before you order.
