Martyr CMR Rudder/Trim Tab Anodes

Seems good

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

Just what it says it is. Comes with hardware.

Used for small outboard motor

item as described, I ordered two items and received one...

Lasts way longer than most anodes!

Attempting to get insights regarding new zincs without copper stub - assumed to provide better or solid anode surface contact for anode protection. All old zincs I notice had the copper stub. None of these Amazon zincs have it. See picture for comparison. Curious. Will monitor anode performance over time and adjust all ratings accordingly.

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

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

very high quality
