Troubleshooting & FAQ
How do I know if this bushing fits my drive?
This bushing is specifically for Volvo Penta DPH and DPR sterndrive models. The most reliable way to confirm fitment is by matching your old part number to 984225. Also, check the compatibility table on this page.
What are signs of a failing inner ring bushing?
Symptoms of a worn or failed bushing can include excessive vibration from the sterndrive, unusual gear noise (whining or grinding), or visible metallic shavings in the gear lube during a change. It is often replaced during a comprehensive lower unit rebuild.
Can I install this bushing myself?
This part requires press-fitting, which necessitates specialized tools (a hydraulic press and correct-sized drivers). Improper installation can damage the bushing or the gearcase. Professional installation is strongly recommended unless you have the correct tools and experience.
How often should this part be replaced?
There is no fixed replacement interval for this bushing. It is a durable component typically replaced only when signs of wear appear or as a preventative measure during a complete sterndrive or gearcase overhaul.
Is this part the same as the outer ring?
No, this is the inner ring bushing. Drives often have multiple rings and bushings. Verify the part number and its position on an exploded-view diagram for your specific model before ordering.

This listing is an aftermarket replacement (not OEM). It's built to OEM-level specifications with comparable materials. It is manufactured in an ISO 9002 facility and batch-inspected for consistency and quality.
