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.

Regular inspection of a yacht’s manual bilge pump is essential for ensuring reliable operation and preventing costly repairs. Unlike electric bilge pumps, manual bilge pumps provide a critical backup that doesn’t rely on electrical power. However, to remain effective, manual bilge pumps require routine inspections and maintenance to address wear, blockages, and other issues that may compromise their performance. YachtService.me specializes in thorough manual bilge pump inspections and repairs, helping yacht owners maintain safety at sea.
