3803889 Servo Unit Reman | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured steering unit servo, listed in the reman catalogue as the SUS for IPS1-A with EVC-B to EVC-B2, weighing 0.919 kg and covering five applications across the D and IPS series. It supersedes 3803837. The EVC generation is the whole decision here: the catalogue lists 3801113 for IPS1-B on EVC-C up to serial number 3194005811, 3801461 for IPS1-B to IPS1-F on EVC-C and EVC-D from serial number 3194005812, and 3801475 for IPS1-F on EVC-E. This unit is supplied on an exchange basis: core deposit 3806889 is charged alongside it and refunded once the old unit is returned, so both numbers appear on the order.

🔌 Function

Turns an electrical command from the electronic vessel control system into mechanical movement, driving the steering and control linkage to the position the system asks for.

⚠️ Common Signs of Failure

• Steering or shift not following the helm
• Slow, jerky or noisy actuator movement
• The control system dropping into a limp or safe mode
• Actuator or position faults logged by the electronics
• Movement stopping short of full travel

🛠️ Service Notes

• Confirm the boat is on EVC-B or EVC-B2 before ordering, because the other three servo units cover later generations
• The published 0.919 kg is far below the 8.07 kg and 12.91 kg carried by the other two servo units listed here, so do not use weight to identify it
• Prove the harness, connectors and supply voltage before condemning the unit, and relearn the travel limits after fitting if the system asks for it
