Before you buy — quick checklist

  • Confirm your existing pump is the Marlow Gemini Plus II and matches model number 0059F88C on the label
  • Verify your spa runs on 115V — do not install on a 240V circuit
  • Check that your plumbing union sizes match this pump's inlet and outlet ports before ordering
  • Confirm your spa control system is a Balboa Gemini Plus II — this is an OEM-matched part
  • Inspect the wet end and motor separately — if only one is failed, you may not need the full pump assembly

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
