# 3801905 Engine Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Remanufactured engine 3801904 shares the same published weight and series, so the bulletin and the part number are what separate them. This unit is supplied on an exchange basis: core deposit 3804905 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
