About This Part
Genuine Volvo Penta 655 (3849500) is an OEM drain plug used to seal inspection ports, drain openings, or unused connections on select Volvo Penta marine engines. Note: Volvo Penta has superseded this part number to 21114522. If 21114522 is available, it is the current service replacement. Part 655 / 3849500 may still be used where diagrams specifically call for it and the original specification has not changed.
Compatible Applications
- Select Volvo Penta marine inboard engines — drain port and plug sealing applications
- Confirm fitment using your Volvo Penta engine serial number and the applicable parts diagram
Always verify fitment using your engine serial number and the exact Volvo Penta parts diagram before ordering.
Supersession Notice
Volvo Penta has replaced part number 655 / 3849500 with 21114522. We recommend ordering the current part number unless your service diagram specifically calls for the original.
When to Replace
Replace this plug whenever the drain or port is serviced, if the plug shows signs of corrosion, thread damage, or a compromised sealing surface, or if it no longer seats and seals properly after tightening.
Installation Notes
Inspect the mating threads and seating surface before installation. Install to the torque specification listed in the Volvo Penta service manual for the applicable engine. Do not overtighten — thread damage on the engine block is difficult to repair in the field.
Alternate & Cross-Reference Part Numbers
- OEM (original): 655 / 3849500
- OEM (current supersession): 21114522
Parts Desk Insight
This plug is most commonly needed during cooling system service, winterization, or engine drain procedures on older Volvo Penta inboard applications. The most common issue is thread corrosion on the plug itself after years in a saltwater or mixed-use environment — inspect the seating surface carefully before reusing. If you need this for a current service, check whether 21114522 is the right fit for your engine first, as it is the active Volvo Penta replacement.
