If your boat didn’t come with surf ballast — or your stock ballast isn’t enough — Fly High Pro X is the bag the surf community has used for years. Heavy-duty fabric, threaded fittings that don’t strip, and a profile that fits in most rear lockers.

Who it’s for

Boats running aftermarket ballast — I/O sterndrive boats, older direct-drives, or any v-drive that needs more sac than the factory installed.

What we like

  • Construction stands up to a season of fill-drain cycles.
  • Threaded fittings work with most reversible-pump setups.
  • Generous warranty on bags — if it fails, they replace it.

You’ll also need

A reversible aerator pump (for fill/drain), 1” suction hose, and an in-floor or splice fitting for the through-hull. Talk to the shop you trust before you cut into a hull.
