3801780 Control Unit Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured control unit from the Ignition and Control Systems group. It supersedes part number 3801779. The published weight is zero, which is a listing error rather than a real figure, so it is no help in identifying the unit and the part number is what to order by. This unit is supplied on an exchange basis: core deposit 3804780 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

🛠️ Service Notes

• If your records show 3801779, this is the current replacement
• Control units usually need programming to the engine and boat before they will run, so tell us the engine serial number when you order
