Volvo Penta 425784 is a genuine OEM roller bearing used in selected Volvo Penta marine drive applications. Volvo Penta's official parts shop lists 425784 as a current genuine roller bearing, and current replacement-market references consistently place it in propeller shaft / lower unit bearing applications on DPH, DPR, and related sterndrive families. That makes propeller shaft roller bearing the strongest supportable customer-facing description for this part.
Key Features
- Genuine Volvo Penta part number 425784
- Official Volvo Penta description: roller bearing
- Commonly identified in current parts references as a propeller shaft / lower unit roller bearing
- Current dealer weight reference: 0.313 kg
- Best matched by exact drive serial number and schematic rather than appearance alone.
Drive Compatibility
Current public references most clearly associate Volvo Penta 425784 with sterndrive families including DPH-A, DPH-B, DPH-C, DPH-D, DPR-A, DPR-B, DPR-C, DPR-D, DPH-D1, and DPI-A. Because bearing fitment is highly drive-specific and depends on the exact lower-unit assembly, final compatibility should still be confirmed by exact serial number before ordering.
Serial Number Fitment Notice
Volvo Penta bearing fitment can vary by drive model, lower-unit arrangement, and production break. Confirm part number 425784 against your exact drive serial number before ordering. Volvo Penta specifically advises identifying the engine, shield, or drive when selecting genuine parts.
When This Part Needs Replacement
Replace this roller bearing when the original bearing shows roughness, noise, excessive play, pitting, corrosion, overheating marks, or damage found during lower-unit or propeller-shaft service. It is also a smart replacement item whenever the related shaft assembly is already apart and the original bearing shows wear that could shorten service life.
Installation Notes
Install only after confirming the exact application by serial number and parts diagram. Because this is a lower-unit bearing, correct orientation, fit, preload context, and mating-surface condition all matter. Inspect the shaft, housing, and related components before installation, and match 425784 directly to the correct Volvo Penta schematic rather than ordering by appearance alone.
Alternate/Superseded Part Numbers
The current sources reviewed consistently identify 425784 as the key Volvo Penta ordering number. No stronger current public supersession reference was established, so the cleanest genuine ordering reference remains Volvo Penta 425784.
Parts Desk Insight
Bearings like this are not good candidates for guesswork because a lower-unit bearing can look close and still be wrong for the housing or shaft it supports. On DPH and DPR drives especially, matching by exact serial number is the safest move, since similar-looking bearings may sit in different positions within the same drive family. That helps avoid repeat teardown and protects the rest of the lower-unit assembly.
