T&T: Fresh water anodes

[Drew McCrocklin]

Previously I have been a left coast boater and therefore pretty much  
always in salt water. I will be wintering my boat up a river in fresh  
water on the east coast for the first time this year. I have read that  
I need to change my zincs out for magnesium in fresh water. Do people  
really do this or is there a workaround such as adding an extra  
magnesium anode from a wire or some such? There are really a lot of  
different zincs on the boat, hull, trim tab, engine, thruster, spurs,  
etc. I have seen lots of references to the where the loopers lower  
there masts, etc. but no references to where they haul/dive to change  
all their zincs to magnesium for the time in the lakes. Any advice or  
experience appreciated.
