Volvo Penta is now of­fer­ing its Ac­tive Cor­ro­sion Pro­tec­tion (ACP) sys­tem for stern­drives.

ACP al­ready safe­guards Volvo Penta’s In­board Per­for­mance Sys­tem (IPS) drives.

Sacri­fi­cial an­odes of mag­ne­sium, alu­minum or zinc are con­sumed over time and could wear away at any point with­out warn­ing, leav­ing the drive at risk of cor­ro­sion.

ACP ap­plies im­pressed cur­rents through a tran­som unit, con­tin­u­ally mea­sur­ing and ad­just­ing the elec­tri­cal out­put, for ideal pro­tec­tion from gal­vanic cor­ro­sion. It re­places the need for sacri­fi­cial an­odes on the drive in brack­ish and salt wa­ter.

Volvo Penta’s ACP sys­tem is fully in­te­grated into the boat’s Elec­tronic Ves­sel Con­trol (EVC) and pow­ered by the boat’s aux­il­iary bat­tery, backed-up with shore power when at the dock.

The ACP pack­age in­cludes a con­trol unit, a tran­som unit and a back-up sacri­fi­cial an­ode.

Volvo Penta’s ACP is com­pat­i­ble with Volvo Penta stern­drive en­gines with EVC in sin­gle and twin in­stal­la­tions. It can also be retro­fit­ted to en­gines pro­duced from 2007 with EVC gen­er­a­tion C2 or later.
