Anode on Allterrain

[Simmsy]

Can anyone give me some info on the pros and cons of attaching a sacrificial anode on to a Minn Kota Allterrain.
I would also like to know where you would mount the anode?
On the shaft or at the bottom of the prop-weed guard area?
Thanks all.

Our last All Terrain never had a sacrifical anode and worked fine for 3 years, in fact it is still going and working fine with it's new owner.

JP did attach a fuse (I think), but that was all.

I am sure he will give you his 2 cents worth when he wakes up (just having a cat nap).

The new All Terrain doesn't have a sacrifical annode attached either. I think they are meant for the Riptides as the All Terrains are cable driven, not servo driven like the Riptides.

Would you say that the AT's would go ok in the Swan as long as I clean it down properly after each use?

I have a freshwater motorguide that I have had for at least 18 months used regularly that is still in mint condition.The anode I attached doesn't even show any signs of rust.As long as you give it a good rinse with fresh water ( I use a bit of car wash as well just to be sure ) after every use and keep moving bits well greased it will handle the salt fine.

I have the AT 55. I put a sacrificial annode on it. I put the prop nut annode on it. If they are washed and looked after like has already been said it should be no worries.

Thanks for your help there guys, much appreciated.

What about electrolysis? Minn Kota describes the cause of galvanic corrosion as the voltage difference created between dissimilar metals in a conductive media (like saltwater). In other words, stick two different types of metal into an electrolyte like saltwater and you make a sort of weak, self-destructive battery. Minn Kota’s composite shafts are not metal and don’t conduct electricity, so they eliminate the possibility of galvanic corrosion between the shaft and lower unit. Such a small amount of metal is exposed on the lower unit that a sacrificial zinc anode washer between the prop and prop nut is all that’s needed to provide corrosion protection.

Just did a search on Google and came up with the above.

As I said before, there is no need to attach a sacrifical annode to a cable driven motor, for the reasons decribed in the above link. The motor described in the quote was a Riptide, not a cable steer.

Hope this helps

Yeah cheers for that. Sounds like the go.
