Out Drive Corrosion Volvo Duo Prop
 

iam located in michigan and have a volvo duoprop stainless steel props I have painted and repainted my outdrive . A it stil continues to have paint chip or flke off .Also iam seeing signs of corrosion on the outdrive.

Any suggestions i dont plug it in to shore power at all.while its in the water

sacrificial zinc anodes need to be replaced every year. If there is shore power in your marina someone elses bad ground can still mess with you but new zincs will help.

He is absolutely correct.

The other thing to check is your own grounds and make sure they are secure and making contact.

Power bleeding into the water from your or other boats is the primary casue of corrosion.

You can have more than one annode per drive. They make the round ones that clamp onto your hydraluic trim cylinder. Once you see them getting chewed up replace them.
