Volvo Penta’s Active Corrosion Protection negates the need for sacrificial anodes.

Volvo Penta introduced Active Corrosion Protection for sterndrives from corrosion in the water. The system has already been available for its IPS drives.

“We are the first company to provide complete corrosion protection with an active system,” Jonas Welinder, product planner for marine electronics, said in a statement. “Its development has been driven by customers wanting an easy solution to prevent their drive units from corrosion.”

Volvo Penta said the system is an alternative to protecting components with sacrificial anodes, which require periodic replacement.

ACP uses impressed currents through a transom unit to continually protect drives from galvanic corrosion, measuring and adjusting the electrical output for brackish and salt water. The system is integrated into Volvo Penta’s Electronic Vessel Control and lets the boat owner monitor the protection status on a helm screen.

ACP is compatible for sterndrives with EVC in single and twin installations and can be retrofitted on engines produced from 2007 with EVC generation C2 or later.
