We have a 280 currently kept in the Great Lakes and debating moving down to South Carolina and keeping it in an estuary with brackish water. How much of a problem will the mercruisers and B-3's be (related to corrosion).

You will get various responses to this, here’s my experience.
My 2007 with Bravo3 has been wet slipped in salt water 6 months per year for its entire life.
Myself and the previous owners have replaced the aluminum anodes yearly, and painted the drive each spring before launch.
There is no corrosion anywhere on the drive. The horseshoe shaped anode on the forward edge of the cavitation plate takes the most abuse and only lasts one season. The others aren’t so bad, but they all get replaced yearly regardless.
Every winter the drive is removed and the upper/lower units separated to clean the 2-3 barnacles that grow inside there each season.
The original manifolds, risers and bellows were replaced at 11 years and 300 hours.
Does your 2005 have the additional prop shaft anode? Seems that the older B3’s, around 1999 or so, had corrosion issues.
The aluminum anodes are for salt/brackish water, I assume you have something else on there now for your fresh water application.
