# 21166098 Retainer | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta retainer weighing 0.769 kg, listed for the D8, D11 and D13 marine engines and the IPS drive range - including D8A2-A MP, D8A3-A, D11A-C, D11B4-A MP, D13C4-A MP, D13C6-A MP, IPS2-A, IPS3-A, IPS15-A, IPS20-D, IPS30-D, IPS510, IPS650 and IPS950.
