3804874 Inboard Drive Core | Genuine Volvo Penta Part

🔧 Product Description

Booked as a deposit and not as a part, this line carries the refundable charge made against the old inboard drive at the moment an exchange inboard drive is bought. It supplies no hardware of its own. Volvo Penta numbers a core deposit 3000 above the unit it belongs to, which puts this one against 3801874. We do not list 3801874 ourselves, so order it through the supplier of the exchange inboard drive. Near-identical inboard drive deposits sit alongside it, among them 3804917 and 3804918, and nothing in our records separates one from another, so order by the number of the inboard drive being exchanged. The charge comes back once the old inboard drive reaches us.

⚙️ Key Features

• Refundable core charge, not a part that ships
• Sits against unit 3801874, which we do not list
• Raised against the old inboard drive on an exchange purchase
• Near-identical siblings include 3804917 and 3804918
• Credited when the old inboard drive is returned

🔌 Function

Carries the refundable core charge on an inboard drive exchange. The line itself supplies no hardware; the drive it stands against takes the engine's output through the transom and turns it into thrust at the propeller.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the inboard drive being exchanged
• Whine, growl or rumble from the drive that rises and falls with speed
• Grey or milky oil drained from the drive, showing water has got in
• Vibration felt through the hull, or a clunk when a gear is engaged
• Chipped or pitted gear teeth, collapsed bearings or scored shafts on strip-down

🛠️ Service Notes

• Ordering this line on its own supplies no inboard drive. It is the deposit that rides alongside the exchange unit, so the inboard drive itself has to be ordered as a separate line.
• The charge is refunded when the old inboard drive comes back to us complete and rebuildable; a unit that has been stripped for parts, broken up or damaged in transit is normally refused for credit.
• Drain the drive and return it complete with its gearcases joined, and check the bellows, gaiters and shift linkage while the drive is off the transom.

📦 Condition

• Refundable core deposit - not a physical part
