23481462 ACP Kit, Active Corrosion Protection, Twin Installation | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Active Corrosion Protection kit for a twin or triple Aquamatic sterndrive installation, EVC 2. Volvo Penta's ACP (Active Corrosion Protection) system is an advanced, fully integrated solution designed to safeguard sterndrives and IPS pods from galvanic corrosion, significantly reducing maintenance and enhancing boating convenience. The system uses impressed current cathodic protection (ICCP): it constantly monitors the electrical potential and carefully adjusts the output to the transom unit in relation to this.

🔌 Function

The controller regulates protective current around both drive systems by impressed current and reports corrosion protection status to the EVC display.

⚠️ Common Signs of Failure

• One or both drive channels showing a protection warning
• Unequal protection caused by a damaged drive-side assembly
• Bonding or harness continuity fault
• Control unit power or network communication failure
• Corrosion continuing because installation, hull isolation or calibration is wrong

🛠️ Service Notes

• Confirm the generation before ordering: the EVC C2 to EVC E twin kit is 23254031, and this is the EVC2 twin package
• The system suits fibreglass hulls with EVC generation C2 or later and a 2.5, 4 or 7 inch display or Glass Cockpit
• No anodes are consumed while the system is active, so check both back-up anodes at every lift as a measure of how well the system has been working
• Requirements: a Volvo Penta IPS or an Aquamatic DPI, DPH, DPS, SX, OX, FWD or DPR sterndrive; Electronic Vessel Control generation C2 or later; a 2.5in, 4in or 7in EVC display or Glass Cockpit; and a fibreglass hull
• Twin Aquamatic sterndrive installations are supplied with two back-up anodes
• Extra bonding cable is needed between IPS units on triple and quad installations - one for a triple, two for a quad
• Volvo Penta recommends keeping shore power connected while berthed
• Below 75% battery state of charge with no shore power the system enters a monitor-only mode: status is still visible at the helm but protection comes from the back-up sacrificial anodes
• Below 50% battery state of charge the system is inactive and protection comes entirely from the back-up anodes
• Typical consumption is under 350 mA for a triple IPS1/10 installation with unpainted drives; with painted drives that can fall below 50 mA
• Always follow Volvo Penta's instructions for painting IPS drives, and the legislation governing antifouling paints where the boat is used
