Troubleshooting & FAQ
How do I know if this collar fits my specific engine model?
This part fits hundreds of Yamaha models from 115-300HP (1990-2016) and select Mercury 225 EFI engines. Always check the compatibility table on this page against your engine's model, year, and serial number. When in doubt, compare the part number 61A-45527-00-00 to your service manual.
Is this collar difficult to install?
Installation requires removing the outboard's lower unit and disassembling the water pump. While it can be a DIY job for those with mechanical experience, we recommend professional installation to ensure correct assembly and function.
What are the signs of a failing drive shaft collar?
A worn or broken collar can lead to loose components on the drive shaft, causing unusual noises from the lower unit, vibrations, or potential failure of the water pump to circulate coolant effectively. It is typically replaced as part of a complete water pump service.
Do I need to replace anything else with this collar?
Yes, this collar is often used with a corresponding spacer (Yamaha P/N 61A-45538-00-00) and sometimes anti-knock washers. While these are separate parts not included here, it's crucial to inspect and replace them if they show signs of wear during your water pump service.
