Martyr CMR Rudder/Trim Tab Anodes

This works much better than the previous model....

So far so good. These were direct replacements of the zincs I had in place. Been on for awhile now. I would definitely recommend them to friends.

Fine

My other anodes last more than twice as long as these, but these are round with a hole in the middle that fits my application better. Will probably have to buy again if I caant find something better.

It was delivered fast and they are great but only received one of the two zinc discs . The tape in the amazon box was loose on top and must have fallen out

Needed these to put on our trim Tabs . Needed them quickly to put our boat in the water for the season . They arrived in one day .

Quick deliver and solid product.

If you have your boat sitting in the water for any amount of time its a must to protect from electrolysis. They advertise 2 at this price but its 2 halves. Amazon made it right as always

Only came with half of it.

Easy installation and good quality
