BFI Bronze Hull Kit 1-1/2in (3 part kit) (O8011-KIT)

BFI 1 ½” Hull Kit(O8011-KIT):
If you’re plumbing in your own ballast system you’ll want to include a thru-hull check valve as part of it. You may be able to get away without one but for a proper ballast system where you can fill and drain from above or below the water line a check valve and venting should be used. The BFI Kit is everything you need to add one to a ballast system using 1 ½” hose.
