I'll be using the Bravo 1 drive that came with my 25 along with a shiny new 350 Mag MPI. This is my first sterndrive boat, and I want to get familiar with the potential problems so I can do appropriate preventive maintenance. Any info experienced sterndrive owners can provide is appreciated.

that was the older bravo III drives - not an "electrolysis" problem - galvanic corrosion - electrolysis,that's hair removal...
problem came from the prop shaft carrier,too much stainless steel...
since been corrected...
you need to be carefull with those older bravo drives/transom plates - the water transfer hose - there's a bushing,it will become restricted,from salt intrusion,end result is a low water/distrurbed water flow
