Default 2014 Yamaha F70 internal anodes

I replaced the anode on the port side of the motor, but there are three more - one between each of the spark plugs (part number 6G8-11325-00-00) that I've been told need to have the head removed to replace. Looking at the parts diagram would make me question that. Has anyone changed these and if so how did you have to go about doing it? Reading the question on the F250 in another thread made me want to ask about the experiences here (one person said that you didn't need to pull the heads to do this replacement and one was told you needed to).

Well they are removable without taking of the head There are no internal zincs that I cannot reach easily - thankful for that!

Those things that look like stainless bolts between the cylinders hold the zincs. Once you get them out there is a screw that holds them on the bolt looking carrier.
These may be the most important zincs to replace regularly since they get eaten the fastest. Be sure to get new gaskets too.

Yes, those are the ones. The one I took out looks in good shape, but I've yet to take the other two out. The lower one might be worse. I'll get the o-rings and anodes Monday and replace them all.

How many hours? Those are around 600.and they are at least half gone. The other internals looked almost new. I think the difference is the rest are running in cold water. These are in hot water.
I order them online and they are pretty cheap that way.

240 hours/4 years. The one I took out looks good. It is a little rough feeling in the fingers, as it is pitted a bit. Definitely more material than the ones you've shown.

You need to get out more
I have about 1400 hours on my 2012 F70.
I will be doing my 3d set of anodes next time it is on the trailer.
The best way to figure out how bad they really are is to soak them in vinegar overnight to get the white salts off of them and then weigh the metal that is left. A brand new one seems to be around 0.4oz.

I try I try! You know the summer here is not always conducive to boating. I retired in late 2016 and supposedly have more time, but as you know there is plenty to do “out here” and it doesn’t always include the water. Getting ready for an Everglades trip for mid March so that should add some hours. 😎

Trailer boating can be tough in the summer because you are not sure how the weather will be by the time you get where you are going. For us it is easier since the boat is behind the house and we don't need much of a commitment to get out there. If it blows up on us we can run home.
