VOLVO PENTA PROPELLER & SAILDRIVE ANODES

Description

These VOLVO PENTA PROPELLER & SAILDRIVE ANODES are manufactured a high-quality anode specification. All the VOLVO PENTA PROPELLER & SAILDRIVE ANODES we sell are suitable for use in salt and brackish water.

• Volvo Penta™ Anode Kit CM3858399KIT is a 3-piece anode for folding propellers.
• Volvo Penta™ Anode CM358407 is a 2-piece anode for SD 130/150 2002 2003 series saildrives. 
• Volvo Penta™ Anode CM851983Z is a one-piece anode for 120 series saildrives. Notice: the propeller has to be removed to change this anode.
• Volvo Penta™ Anode CM875812Z is a one-piece anode for the 110 series saildrives. Notice: the propeller has to be removed to change this anode.
• Volvo Penta™ Anode CM852018Z – a two-piece zinc anode for 2-blade folding propellers (part numbers 852098 to 99 and 851061 to 851064) used with 110/120, S-B and S-C series Volvo Penta saildrives.

These anodes offer excellent cathodic protection and help control and prevent the corrosion of metals, particularly the propeller on your boat. The zinc anodes are for salt water use – they are not recommended for fresh water use.

Fit the correct anode material for the waters in which your boat operates. Anodes should be replaced when they are 70% eroded.

As a general rule boat owners should fit the anodes suitable for the environment they most regularly berth in and the following provides a useful guide:

• Salt Water: Fit Aluminum (Premium) or Zinc (Traditional) anodes
• Brackish Water: Fit Aluminum (Premium) anodes
• Fresh Water: Fit Magnesium (Fresh) anodes

Some vessels will from time to time move between salt and fresh water, others are berthed within marinas and behind tidal barriers where the water is enclosed and likely to be brackish or even virtually fresh. Owners must be aware of the effects that this may have on their boats and fit the correct cathodic protection system to avoid corrosion.

Not all anodes are suitable for every environment, for example the surface of a zinc or aluminum anode will, if left in fresh water for
some time, become covered with an off-white crust of oxide which effectively seals the anode and stops it working even when returned
to salt water.

Zinc anodes suffer a similar problem even in brackish conditions whereas aluminum will continue to operate effectively in river estuaries
and other areas of brackish water indefinitely. The consequences of this passivity of the anode are that the next most anodic item within the anode bonding system will start to sacrifice itself which could of course be very serious

Martyr Anodes:

Martyr Anodes provides high-quality, low-cost marine cathodic protection for boats, engines, outboards, and marine equipment. Often called “boat zincs”, Martyr Anodes are made of a specialized alloy based on the US Mil Spec using only high purity metals. The company is the only manufacturer that offers all three alloys that protect your boat from corrosion that can occur in salt, brackish, and fresh water. All their anodes are pressure die-cast and follow strict quality standards through an ISO 9001 Quality Management system.

Martyr manufacture sacrificial zinc, aluminum, and magnesium anodes, all of which prevents boat corrosion that leads to pitting to the hull plate, rudders, and keels. Martyr anodes also protect propellers, shafts, shaft brackets, stern tubes, engines, and rudders. Their anode kits include all the necessary installation hardware and instructions.

CMP Group traces its roots back to a foundry established in the early 1900s in Vancouver, initially serving the region’s plumbing and forestry industries. Leveraging its expertise in non-ferrous metal casting, the company ventured into the commercial marine market, developing high-quality zinc and aluminum anodes. This marked the beginning of CMP’s transformation into a trusted global supplier of die-cast anodes for the marine pleasure craft industry.
