3804996 Engine Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an engine, from 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 3801996, which is the number to quote for the engine itself. It is listed for one application in the D series. Three further engine cores sit in this run - 3804997, 3804998 and 3805000 - and no weight is published against any of them, so the part number is the only thing that separates one from another. Order the number the exchange engine was quoted against.

⚙️ Key Features

• Refunded when the old engine is returned
• Listed for one application in the D series
• Engine group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the engine itself is the complete power unit, turning fuel into the shaft power that drives the boat and the engine-driven services hung off it.

⚠️ 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
• Heavy blue smoke and oil use climbing hard, with breather fumes and pressure showing at the filler
• Low or uneven compression, hard starting and power well down on what the boat used to do
• Knocking, rumbling or a deep tapping from the bottom end that rises and falls with load
• Coolant and oil mixing, or exhaust gas showing in the cooling system

🛠️ Service Notes

• The charge is refunded when the worn engine is returned, so keep the old unit complete and send it back rather than breaking it for parts, since a stripped core is normally refused
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3801996
• Establish what killed the first engine before the exchange goes in: a fouled raw water circuit, a failed heat exchanger, a lean or contaminated fuel supply or a misaligned shaft will do the same to the replacement, so put the cooling, fuel and alignment right at the same time

📦 Condition

• Refundable core deposit - not a physical part
