Galvanic.corrosion; Corrosion.prevention - Four winns FUNSHIP Owner's Manual

B. Galvanic Corrosion
Galvanic.corrosion.results.from.a.potential.electrical.
difference.existing.between.dissimilar.metals..
immersed.in.a.conductive.solution.(e.g.,.salt.or.
brackish.water)..If.these.metals.touch.or.are.otherwise.
electrically.connected,.this.potential.difference.pro-
duces an electron flow between them. The attack on
the.more.active.metal.is.usually.increased.and.the.
attack.on..
the.less.active.metal.is.decreased,.as.compared.to.
when.these.metals.are.not.touching.
C. Corrosion Prevention
Anti-corrosion.anodes.are.attached.to.the.bottom.of.
the.gimbal.housing.to.prevent.corrosion.to.your.stern.
drive.and.underwater.parts..These.anodes.will.be.
slowly.eroded.away.by.galvanic.action.and.require.
periodic.inspection..Please.refer.to.the.section.on.
"Anti-Corrosion.Anodes".or."Corrosion.and.Corrosion.
Protection".in.your.engine.manufacturer's.manual.for.
additional.information..The.engine.manual.is.included.
in.the.owner's.packet.
