Boat Drive Train, Shaft Packing & Stuffing Boxes

Fisheries Supply stocks a wide range of stuffing boxes, shaft seals and stern gland components from leading manufacturers. We understand the critical role watertight drivetrain seals play onboard vessels with inboard power or rudder stocks penetrating below static water lines. That's why we supply time-tested marine stuffing boxes and packing proven over decades to contain leaks safely. Brands such as Buck Algonquin and Johnson-Duramax engineer robust stuffing box solutions capable of handling constant engine vibrations and shaft thrust forces within cramped engine spaces over thousands of hours without failure. Our sales representatives can help determine the appropriate replacement based on existing configurations or new installations. We also provide strained cutless bearings, shaft couplings and accessories indicated to complete drivetrain service and upgrades this offseason. Trust Fisheries Supply for reliable shaft seals preventing excessive bilge pumping and protecting onboard machinery through long voyages offshore.
