# 3804763 Engine Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for an engine, in the Engine group. It is the refundable charge raised against the old engine when the exchange unit is bought, and it comes back once the worn engine is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3801763, which is the number to quote for the component itself. It is one of 9 engine cores running through this block, and nothing published against them separates one from another, so order the number that matches the engine actually coming off rather than working from the description. Longblock and shortblock cores sit in the same block and cover less than a complete engine, so check what is actually being exchanged before this number goes on the order.

## ⚙️ Key Features

-   Core deposit line, not an engine you can fit
-   Belongs with the exchange unit, part number 3801763
-   Refunded when the old engine is returned
-   Not separable from the other engine cores here, so order by part number
-   Engine group

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the engine itself is the complete unit being exchanged, taken back for remanufacture and replaced as a whole rather than repaired in the boat.

## ⚠️ Common Signs of Failure

-   This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the engine being exchanged
-   Will not make its rated revs or power, and smokes heavily doing what it used to do easily
-   Knocking or rumbling from the bottom end, with oil pressure low once it is hot
-   Heavy breathing from the crankcase, coolant and oil mixing, or water where it should not be
-   On strip-down, scored bores, worn shells, a cracked block or head and metal through the oil system

## 🛠️ Service Notes

-   The charge is refunded when the worn engine is returned, so keep the old unit and send it back rather than scrapping it
-   Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801763
-   Return the old unit as complete as it came off, since missing ancillaries and a stripped core are the usual reasons a deposit is not refunded in full

## 📦 Condition
