21116404 Reversing Gear | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Complete Marine Reversing Gear - Part Number: 21116404

Complete genuine Volvo Penta hydraulic marine reversing-gear assembly. Public parts data confirms the complete assembly number but does not safely establish the transmission model, reduction ratio or flange configuration. Those specifications must therefore be matched from the original transmission identification plate.
