I had a nice weather day yesterday so decided to get a head start on spring 
projects.  Nothing went smoothly (what else is new):

#1- I tried to replace the Raritan water heater anode.  This is the first time 
I have tried to do it in the 5 years I have owned the boat, so unknown when was 
the last change.  I was unable to budge the threads at all with a large pipe 
wrench.  Suggestions on how to get it loose without damage to the unit?  Will 
PB blaster do anything to pipe compound?

#2- I removed the engine heat exchanger anode that I put in a few years ago.  
The cap came off without the zinc itself.  I first interpreted this as the zinc 
being completely gone.  However, when I tried to insert a new one, it was 
blocked from going in at all.  I am guessing this means the zinc core broke off 
and is stuck inside.  If I take the end cap off, can I get to the piece inside? 
 Is this a common problem?  

Thanks- Dave
