In this video, I rebuild our NAVTEC hydraulic backstay tensioner while at anchor in La Paz, Mexico.

For ordering the correct rebuild kit for your unit, first reference the stampings on your unit then check for the correct seal kit at the following website:

Then reach out to a NAVTEC dealer who can send you the kit.

I recommend reaching out to Alan at Seatek Yachting in Long Beach, CA. He was extremely helpful.
