Mercruiser electrolysis / merCathode ?

[abl1111]

Anyone here familair w/ the inherent problem w/ Mercruiser's Bravo 3 drive electrolysis ? ( This question is for people who keep their boat in the water - not dry stored ).

Do you have a MerCathode installed ? Does it work well ? Does this cathode have to be replaced or is it a permanent thing ? Is the Bravo 3 worth the extra hassle of having to always be plugged into shore power for protection ?

Thx,

Alan
