Cutlass Bearing Replacement: Expert Insights from Yacht Technicians in Montenegro
A yacht’s propulsion system relies heavily on a small but crucial component — the cutlass bearing. This bearing supports the propeller shaft, ensuring smooth rotation and preventing vibration. However, continuous operation in saltwater inevitably wears it down. When the bearing begins to fail, symptoms like noise, vibration, or fuel inefficiency can quickly follow.
At YachtService.me, based in Tivat, Montenegro, our certified yacht technicians specialize in cutlass bearing replacement and precision alignment, ensuring optimal performance and reliability across all yacht sizes.
Why Regular Cutlass Bearing Maintenance Is Critical
The cutlass bearing’s inner rubber or polymer lining is water-lubricated, designed to minimize friction and wear. Over time, exposure to seawater, sediment, and vibration causes this lining to degrade, leading to potential damage to the shaft and propulsion system.
Regular inspections and maintenance deliver multiple benefits:

Why Regular Cutlass Bearing Maintenance Is Critical
The cutlass bearing’s inner rubber or polymer lining is water-lubricated, designed to minimize friction and wear. Over time, exposure to seawater, sediment, and vibration causes this lining to degrade, leading to potential damage to the shaft and propulsion system.
Regular inspections and maintenance deliver multiple benefits:
- Reduced vibration and noise during cruising.
- Improved fuel efficiency due to smooth shaft rotation.
- Protection from corrosion and shaft misalignment.
- Extended lifespan of propulsion components.
Common Cutlass Bearing Problems and Expert Solutions
Our Boka Bay yacht service team frequently encounters recurring cutlass bearing issues. Below are the most common problems, with professional solutions provided by our yacht service in Montenegro.
1. Excessive Vibration and Noise
Vibration often signals uneven wear or misalignment. Our technicians use precision tools to remove the worn bearing, perform shaft alignment, and restore stable operation.
2. Bearing Wear and Shaft Misalignment
A misaligned shaft accelerates bearing wear. We conduct laser alignment checks and fit the bearing perfectly to prevent premature failure.
3. Corrosion from Saltwater
Even high-grade metals can corrode in seawater. YachtService.me installs marine-grade cutlass bearings resistant to corrosion and electrolysis.
4. Shaft Damage Caused by Bearing Failure
When a bearing fails, metal-to-metal contact can score the shaft. Our team inspects for damage and repairs or replaces affected components before reinstallation.
5. Fuel Efficiency Loss
Misaligned or worn bearings increase drag, forcing the engine to work harder. After replacement and alignment, clients often report fuel savings of up to 10–15%.
6. Overheating Due to Poor Water Flow
Blocked water channels cause bearing overheating. YachtService.me cleans intake passages and restores proper lubrication flow.
7. Bearing Slippage
If the bearing loosens in its housing, vibration returns. Our team secures the new bearing with precise press-fit installation to prevent future slippage.
8. Rubber Deterioration
Rubber linings break down in warm saltwater. We recommend polymer-based or composite bearings, which last significantly longer under Mediterranean conditions.

When a yacht’s manual bilge pump fails, it’s more than an inconvenience—it’s a potential safety hazard. Recently, a yacht owner in Tivat contacted YachtService.me after noticing that his manual bilge pump wasn’t drawing water efficiently. Our technicians took immediate action, performing a complete inspection and repair to restore the system’s reliability.
Your yacht’s transmission is at the heart of its propulsion system — the link between the engine’s power and the propeller’s thrust. When the transmission operates smoothly, your vessel glides effortlessly through the water. But when issues arise, performance, safety, and efficiency all suffer. That’s why regular transmission inspections are vital for maintaining your yacht’s reliability and longevity.
