SHAFT SEAL 1 1/8″

The Malibu Shaft Seal (1-1/8″) is a genuine OEM-style marine drivetrain seal designed for Malibu and Axis inboard boats using a 1-1/8″ propeller shaft system. It forms part of the boat’s underwater shaft assembly and is responsible for maintaining a watertight barrier where the prop shaft exits the hull.

This component is typically part of a dripless shaft seal system, helping prevent water intrusion into the bilge while allowing the prop shaft to rotate smoothly under load.

Key Features

• Genuine Malibu OEM-style shaft seal component
• Designed for 1-1/8″ prop shaft systems
• Helps maintain watertight integrity at shaft exit
• Reduces water ingress into bilge areas
• Marine-grade construction for long-term durability in submerged conditions
• Used in Malibu & Axis inboard/V-drive configurations (model-dependent)

Fitment Notes

• Malibu uses multiple shaft sealing systems across different years (including dripless and stuffing box styles), so visual confirmation of your existing unit is important
• This part is commonly associated with Malibu’s 1-1/8″ prop shaft drivetrain setups, not 1-1/4″ or newer shaft systems
• If you are experiencing leaks, common causes include:
  • Worn seal faces or bellows
  • Misalignment of engine or shaft
  • Damaged shaft surface or scoring
• Always confirm whether your boat uses a complete dripless seal assembly or individual components before ordering
