⚠️ Common Signs of Failure

• Rumble or vibration from the stern gear that changes with revs
• Shaft movable by hand within the bearing
• Rubber lining perished, swollen or torn away from its shell
• Black rubber crumbs in the bilge below the bearing
• Rapid wear of the shaft where it runs in the bearing

• Rubber bearings rely on water flow, so check the lubrication path is clear before running up
• Check shaft alignment before fitting, since a misaligned shaft wears a new bearing on one side
• The distance between bearing points must not exceed 1,500 mm
