⚙️ Key Features

• Genuine Volvo Penta IPS ACP through-hull fitting
• Designed for fibreglass-hull Active Corrosion Protection installations
• Used in twin, triple or quadruple IPS configurations according to ACP kit
• Requires gasket 21158077 and shim 21157128 in the applicable installation
• Hull thickness, IPS count and EVC generation control the complete kit
• Engine type: Volvo Penta IPS marine propulsion with electronic corrosion protection

🔌 Function

Provides the sealed through-hull mounting and electrical interface required by the IPS Active Corrosion Protection electrode system.

⚠️ Common Signs of Failure

• Water seepage or staining around the hull penetration
• Loose fitting, damaged threads or failed lock nut
• Corrosion or poor electrical continuity at the ACP connection
• ACP warning or reduced corrosion-protection current
• Cracked gasket, incorrect shim stack or damaged surrounding laminate

🛠️ Service Notes

• Requires gasket 21158077 and shim 21157128 specifically for the ACP electrode seal - order both with the fitting rather than assuming a generic hull-fitting gasket will do
• Configuration (twin, triple or quad IPS) and hull thickness both change what else the kit needs, so confirm the complete ACP kit list for your specific installation before hauling out
