Hey guys. Im having to prep my A20 for use in brackish water. Anyone that has a salt series provide some input on where to install the anodes etc? Any help/direction would be grateful. I've searched the web/forums for pics and have come up empty handed. 

Thanks.

my brack this time of year with the rain and high rivers like our Mississippi is 99.9 fresh, it took 6 near and 1 direct hit tropical storms to make our water salty enough to leave a film on boat when wiped down with the water we are in.  that was November.  if your really near coast of a gulf or ocean then maybe.  

@justgary i think is your salt guy

you do have to worry about trailers in our waters when not galvanized like my painted tandem

The biggest step, in my opinion, would be a heat exchanger to get half closed cooling.  I expect that you have a lot more room available to add it, but you didn't specify which engine you have, so only you know what will fit.  The exchanger should come with a replaceable anode in it.  I have an egg anode on my prop shaft, but I'm thinking about removing it because it doesn't really show any deterioration.

Thanks for the feedback. Its a new M5di so I believe the cooling is closed. That being said, I figure a prop shaft and a transom anode will be the best places to start. Im curious if there are any other spots in could install.
