MARTYR Streamlined Collar Anodes - Zinc

Canada Metal zincs are composed of an alloy that meets Mil-Spec MIL-A-18001 for sacrificial anodes. This alloy is mostly zinc, but with measurable concentrations of cadmium (~0.1%) and aluminum (~0.25%).

The additional cadmium causes the anode to erode from the surface inward, which causes a ''sandblasted'' appearance to the surface. When the anode is almost dissolved, it needs to be replaced.

            These anodes are easy to install.

            Clean the driveshaft with a brass brush before installation. A brass brush in a cordless drill works wonderfully.

            An allen wrench is required to install them. Make sure you purchase the correct size and tighten the bolts equally and firmly on both sides to ensure a proper fit and to prevent slippage.

            No threadlocker is included. Would have given these a 5 star rating had the bolts been pre-coated. I recommend using blue Locktite threadlocker to ensure screws can not back out accidentally.

            Life expectancy not evaluated here. Remember, local marina conditions will impact the life of your anodes! Replace them at least once each year.

            Comments about Martyr Zinc, 1"shaft X 2 1/8"dia. 1/8"l:

            Our company has been performing professional diving services in San Diego for 27 years. Our experience with the anode protection provided by Canada Metals is has been nothing short of exceptional. The manner in which the fasteners snug the anode together and the fit to the precise dismeter of the intened shafts is first class and assists in the easy to install. However, owners BEWARE, if you don't use a professional diver or should you decide to install yourself, you MUST ENSURE that the surface in which to mount the new anode is COMPLETLY clean and free of any marine scale, Otherwise any marine growth /scale can and does inped on the ability of the anode to connect or bond so as to enable proper protection for the intented host metal. Anodes (most commonly refered to as zincs, because most andoes are made of zinc), are designed to contain host metal material (zinc), in such a quality so as when the anode wear about the fastners or about 45-50 % worn, the amount of anode material is about equal to the amount of the anode material in the host metal. This is when it is time to replace the andode. Based on the rule of conductivity, electricity will take the least path of resistence and every path of resistence. Electrical current is created with metal is emersed into a chemical (salt water). This minute current called galvanic current, is dissapated thru the corrosion of the metal (the softest metal first). When attaching pure soft metal (zinc) to the host metal or bonding to the host metal vis attaching to the shaft, the current created will first direct it's corrosive actions toward the pure anode at least until there is no difference in the host metal content or anode content of the soft metal. Then, electrolysis (corrosion of the metal) will begin to effect the host soft metals. Most propellers contain the soft metal zinc because when the zinc is combined with the other metals which make up the propeller, the zinc gives the propeller the ability to prevent stress fractures while the propeller is experiencing tremendous stress under power. In other words, the soft zinc prevents the propeller blades from bending. If and when electrolysis starts to effect a propeller, the zinc molecules begin to disolve, leaving the propeller without the essential ingrediant to give the propellers the strength to withstand the stress under power. Electrolysis is not reversable but it can be controled and stopped by ensuring proper anode maintenance. Happy Boating. [@]
