Mercruiser Bravo III Corrosion

This 1999 Bravo III outdrive is suffering galvanic corrosion from operating with aluminum anodes in freshwater.  The prescription:

1) Exposed areas on the Bravo III's aluminum housing need to be scraped, cleaned, primed, and re-painted;

2) Replace aluminum anodes with magnesium anodes;

3) Install magnesium propeller nut anode.
