# 3802427 Lower Gear | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta lower gear from the Marine Propulsion group, weighing 1261 kg and listed for three applications across the IPS and D families. It is apart from the exchange engines, and the matching upper gear is 3802426 at 712 kg. At 1261 kg it needs crane handling and specialist transport, not ordinary cart checkout and parcel delivery. This unit is supplied on an exchange basis: core deposit 3805427 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta IPS40-A
-   Volvo Penta D13C8-B MP
-   Volvo Penta D13C4-B MP

-   **Engine Family:** IPS, D
