Volvo Penta IPS Flow Deflector Ring – 3862454
Part Information
- Part Number: 3862454
- Brand: Volvo Penta
- Official Product Type: IPS Flow Deflector / Diffuser Ring
- OEM Status: Genuine Volvo Penta
- Diagram Position: Position 9 – IPS T/TS Propeller Hardware Assembly
- System: IPS Drive – T/TS Propeller Series
What This Part Does
The 3862454 is the OEM flow deflector ring fitted in the IPS T/TS propeller hub assembly. It manages exhaust gas routing around the propeller hub, reducing the tendency for exhaust gases to interfere with propeller blade loading at low speeds — a condition that can cause propeller ventilation or loss of grip when maneuvering.
Compatible Applications
- Volvo Penta IPS1 with T/TS-series propellers
- Volvo Penta IPS10 with T/TS-series propellers
- D4-powered IPS installations using T/TS propeller hardware
- D6-powered IPS installations using T/TS propeller hardware
Confirm the installed propeller series and drive unit before ordering — Volvo Penta uses different hardware across IPS propeller families. Match by propeller series and drive number, not engine model alone.
Serial Requirements
No serial-number break has been identified for this part in available Volvo Penta documentation. Verify against your Volvo Penta parts diagram using the drive unit and propeller series as primary identifiers.
When to Replace
- Ring is cracked, distorted, or missing
- Corrosion or impact damage has altered the ring's shape
- Propeller service reveals a damaged or deformed deflector
- Exhaust-related propeller ventilation or loss of grip is suspected at low speeds
- Ring was damaged during propeller removal or installation
Installation Notes
Install in the orientation shown in the applicable Volvo Penta IPS T/TS propeller diagram (position 9). While the propeller assembly is disassembled, inspect all surrounding hardware including the propeller cone, locking components, and line cutter area. Use the specified Volvo Penta torque and locking procedure for the complete propeller re-installation.

Technical FAQ
Q: Is 3862454 used on all IPS drives?
A: No. This part is specific to the IPS T/TS propeller system on IPS1 and IPS10 drives. Other IPS drive and propeller combinations use different hardware. Always confirm against the Volvo Penta parts diagram for your specific drive and propeller series.
Q: Can I run without this ring if it's damaged?
A: Not recommended. The flow deflector's shape directly influences exhaust routing around the propeller hub. A missing or deformed ring can contribute to exhaust-related propeller ventilation and reduced thrust control at low speeds.
Parts Desk Insights
This is the part customers often order simply as a "ring" without realizing it has a specific aerodynamic function in the propeller assembly. The most common issue is ordering without confirming the propeller series — the T/TS designation on your propeller blades is the fastest way to confirm this is the correct deflector. If you're in doubt about your propeller series, the drive unit plate and the Volvo Penta parts diagram for your IPS unit are the most reliable references. Inspect the cone and locking hardware while you have the propeller off.
