# 3850594 Kit | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta kit for the upper gear housing, from the Marine Propulsion group, weighing 0.118 kg and listed for 21 applications across the TSK, DP and SX drives. The upper gear housing designation is what places it, so it is not the kit for the lower unit.

## 🚤 Compatibility

-   **Engine Family:** TSK, DP, SX

Full model list at the end of this description.
