Martyr CMR Rudder/Trim Tab Anodes

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

Item as advertised.

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

Initially, I ordered these because they were less expensive than similar zincs available locally. What I did not expect, however, was such quick shipping and such a quality zinc. Seriously, it might sound funny to describe a sacrificial anode as really nice, but these look better than others, have a nice feel to them and I am sure they will more than pay for themselves.

Arrived on time and as advertised. Installed easily.

This item it two pieces sandwiched together. I separated them to use 1/2 on each trim tab. It only comes with hardware for one. I just used my existing bolt for the other half.

Fine

fast shipping,correct item

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.

Solid product. Excellent Delivery. Fair price.
