Movement at the shaft
Noticeable play where the shaft passes through the bearing can indicate wear. The amount and direction of movement need to be checked at the boat.
Boatyard running-gear service
Cutlass bearing replacement
A worn bearing can let the propeller shaft move more than it should. We assess the bearing and strut during your haul-out, then recommend a replacement method based on the boat's running gear and available access.

Know what to look for
When to have the bearing checked
The cutlass bearing supports the shaft inside the strut. Wear may show up as excess shaft movement, unusual noise or vibration, or visible deterioration of the rubber lining. These symptoms can have other causes, so an inspection matters before replacing parts.
Changes underway
New vibration or noise is worth investigating. A bearing is one possible cause among several running-gear issues.
A planned haul-out
If the boat is already coming out of the water, it is a practical time to inspect the strut, bearing and accessible shaft surface.
The method depends on the boat
Strut Pro tooling can reduce disassembly
Our Strut Pro press equipment can remove and install a bearing with the shaft in place on suitable strut and shaft arrangements. That can avoid some of the work associated with pulling a shaft, but it is not possible on every boat.
Before recommending the method, we check bearing access, dimensions, surrounding hardware and the condition of the shaft and strut. If the setup calls for more disassembly or another specialist, we explain that before work proceeds.
The inspection determines the work scope, estimate and whether the shaft can remain in place.
A clear plan for your haul-out
How we approach the job
Send the boat model, yard location, expected haul-out date and any photos of the strut and shaft. We will review the details with you and coordinate access with the boatyard.
See how boatyard work is priced →Inspect and confirm the scope
We assess bearing wear, shaft movement, access and hardware condition before confirming the recommended method.
Remove and replace the bearing
Where suitable, we use press tooling around the shaft. If the condition we find changes the work, we discuss it with you first.
Check the installation
After installation, we check the bearing fit and accessible shaft movement, and discuss any remaining running-gear concerns.
