# 3801904 Engine Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta factory-remanufactured complete engine from the Engine group, weighing 1320 kg and listed for one application in the TAD series. Remanufactured engine 3801905 carries exactly the same published weight and the same series, so the two cannot be told apart on the figures - order strictly by part number against your engine's designation. This unit is supplied on an exchange basis: core deposit 3804904 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
