STAINLESS STEEL BUSHING 682-44322-00

Function and technical context

The 682-44322-00 stainless steel bushing is a support and alignment component that works in the transmission and propulsion systems of Yamaha, Mercury and Mercruiser marine engines. Its function is to maintain the correct position of axles and drive shafts, ensuring that shaft alignment is accurate during operation. A worn or deteriorated bushing causes excessive play in the shaft, which generates vibrations, progressive misalignment and, in severe cases, damage to seals, bearings and transmission accessories. Stainless steel construction ensures resistance to marine corrosion and durability in saline freshwater and saltwater environments.

When to replace this part?

The main symptoms of bushing wear include abnormal vibrations in the stern area, metallic or grinding noises during operation, and excessive play when moving the shaft manually. This type of component should be inspected annually during the seasonal inspection, especially on heavily used vessels or in waters with sediment. Preventive replacement avoids costly transmission repairs and reduces the risk of navigation breakdowns.
