Martyr CMR Rudder/Trim Tab Anodes

good buy

Used for small outboard motor

I gave 4 stars to easy to install becaus although easy to install they came bolted together and i had a vary hard time getting them apart I mounted mine on the transom to protect the bare aluminum hull of my old 50s boat

These are the best quality sacrificial anode‘s for my Robalo R222 that are attached to the trim tabs. I’ve used them before and I will continue to use them every year as they get replaced every year. Best quality in better price than buying them locally. Amazon is great for anything you need. I would buy them again.

Almost the same OD size. Smaller, odd size fastner.

Boat annoids

When I went to put the anode on this weekend i had noticed that one of the anodes must have been a return from someone. it had the bolt broken off in the anode with the bolt attached. It was something i found easier to fix myself by purchasing a new bolt and nut but this should have been caught in packaging

Perfect, as always

Easy to install - more importantly will be easier to remove when replacement is needed.

Yesterday I was delivered an empty amazon box with the end broken out and nothing in it. It doesnt look like someone stole them, just that the box wasnt strong enough and it fell apart. Obviously the zincs dont work at all, since they arent on my boat.
