# 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.

  

⚙️ Key Features

  

• Complete genuine Volvo Penta reversing gear

• Hydraulic forward, neutral and reverse operation

• Supplied as a configuration-specific transmission assembly

• Input, output flange and reduction ratio must match the vessel

• Suitable only where 21116404 is the specified complete gear number
