# 3801621 Longblock Exch | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta remanufactured longblock from the Engine group, built without VCB, weighing 970 kg and listed for 1 application in the TAD series. It is all but indistinguishable from reman longblock 3801620, another without-VCB build at 965.5 kg. This unit is supplied on an exchange basis: core deposit 3804621 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.
