SHAFT SEAL 1 1/4″

The Malibu Shaft Seal 1-1/4″ is a genuine OEM-style underwater drivetrain seal used on Malibu and Axis inboard/V-drive boats with a 1-1/4″ propeller shaft system. It forms part of the boat’s shaft sealing assembly, helping maintain a watertight barrier where the prop shaft exits the hull while allowing smooth rotation under load.

On many Malibu applications, this part is used as part of a dripless shaft seal system, designed to reduce or eliminate water intrusion into the bilge and provide low-maintenance operation compared to traditional packing-style seals.

Key Features

• Genuine Malibu OEM shaft seal component
• Designed for 1-1/4″ prop shaft systems
• Helps maintain watertight integrity at shaft exit
• Reduces bilge leakage in marine drivetrain systems
• Marine-grade flexible construction for vibration and movement
• Used in Malibu & Axis V-drive/inboard configurations (model dependent)

Fitment Notes

• Malibu uses multiple 1-1/4″ shaft seal designs depending on year and drivetrain package (including full dripless assemblies and coupler-style components), so visual confirmation is critical before ordering
• Often paired with related seal components such as:
  • Shaft seal housings
  • Cooling water feed lines
  • Flexible couplers (depending on system version)
• If you are diagnosing leaks, common causes include:
  • Worn seal face or bellows
  • Misaligned engine/shaft
  • Scored or corroded prop shaft surface
• Always confirm whether your boat requires a complete shaft seal assembly or this individual component
