Okay I have a new to me Mirage with twins 1988. It is equiped with 2 merccathode units on it and I have no experiance with them other than they are used to stop outdrive corrosion similiar, I assume, to zinks other than a zinc is just a sacraficial metal so the aluminum does not corrode.
I was wondering if someone could give me an explanation of the cathode system as again I assume it stops corrosion through some sort of electrical induced electrolysis or the attempt to stop it hence the term cathode?
The boat was intended to be on a lift but plans have changed and now will need to be in the water for the summer with possibly a pull every 4 weeks for a cleaning. It is fresh water only but the outdrives do have SS props and SS skeg guards and a SS tie bar so I assume that will play a role. Also it has Batt disconnects and I do not see the cathodes tied to the Batts all the time which I assume they would have to be in order to function with the switch off?
Thanks
Mat
