Let's Talk Anodes............

Post by Natchamp »

Gents,

I need to get some opinions. I need to install anodes on my boat and want to make sure I cover all the bases. I believe I need the following:

Prop Shaft - collar anodes
Rudder - disc anodes
Trim Tab - anodes (same as rudder anodes?)

Am I missing anything? I was thinking about things like the swim platform brackets but can't recall seeing them installed in any pictures anywhere so I don't know if that's a regular thing to do.

What type id best for salt water? I see anodes in Zinc, Aluminum, and Magnesium.


Also, what the heck is this?

They appear to be sacrificial but I'm not sure. They are threaded and screw onto studs that secure the rudder shaft pillow blocks (see pic below).

I don't see these types of anodes that are threaded so I'm not sure if it's just a "nut" or some type of anode.

+1 for Zinc. Aluminum and Magnesium are too reactive for salt water.

If you have Crusaders with fresh water cooling do not forget the pencil ones in the heat exchanger.

And the pencil zincs in the oil cooler ! But , had a overheating issue last season due to zinc in the cooler doing its job and clogged up my cooler. While at Lankford Bay meet up I removed it and cleaned out the cooler and did not put back in as recommended by the mechanic there. Temps. are good now. Seems I had read somewhere recommending replacing these every 30 days.

I would think you should have attaching bolts somewhere on the transom to install a large diver dream or similar that your bonding system will run to.
For salt water, use zinc.

I would put the zincs back in and change them more often .
