MALIBU 1-1/8" WATER COOLED SHAFT SEAL
Pickup available at 130-134 Sir Donald Bradman Dr
Usually ready in 1 hour
The Malibu 1-1/8" Water Cooled Shaft Seal is a genuine OEM dripless shaft sealing system used on Malibu and Axis inboard boats equipped with a 1-1/8" propeller shaft. It is designed to seal the prop shaft where it exits the hull while using raw water lubrication/cooling to reduce heat and friction at the seal faces.
This system replaces traditional stuffing boxes and provides a more modern, low-maintenance solution that helps keep the bilge dry while allowing smooth shaft rotation under load.
Key Features
- Genuine Malibu OEM water-cooled dripless shaft seal system
- Designed for 1-1/8" prop shaft applications
- Uses water lubrication/cooling for seal face performance
- Helps prevent bilge water intrusion
- Reduces maintenance compared to traditional packing-style seals
- Marine-grade construction for continuous submerged operation
Fitment Notes
- Commonly used on Malibu systems with 1-1/8" drivetrain setups and factory dripless sealing
- Requires proper alignment between engine, shaft, and strut for correct seal life
- Some versions are supplied as a complete assembly or serviceable front seal variant, depending on configuration
- If leakage occurs, typical causes include:
- Worn carbon/face seal surfaces
- Air trapped in cooling line (loss of water lubrication)
- Shaft scoring or corrosion
- Misalignment of drivetrain components
