# 872863 Aquamatic Drive | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta Aquamatic sterndrive unit for the 2.30:1 ratio, from the Marine Propulsion group, weighing 58.967 kg and listed for eight applications across the TMD, AD, DP and TAMD series. It supersedes 3803224 and 872780, catalogued earlier as a drive and a reconditioned Aquamatic drive. The other 2.30:1 drive in this run is 872784, which replaces a different set of numbers and is listed for five applications - the ratio alone will not separate them, so match the number your engine is recorded against.
