Information:

You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Zinc Rods
Corrosion in sea water circuits can result in premature deterioration of system components, leaks, and possible cooling system contamination. The cause for the accelerated corrosion may be the lack of sacrificial zinc anodes (rods) in the sea water system.Zinc rods are inserted in the engine's sea water cooling system to help prevent the corrosive action of salt (sea) water. The reaction of the zinc to the sea water causes the rods to deteriorate, instead of more critical engine cooling system parts. Rapid deterioration of zinc rods may indicate the presence of stray electrical currents from improperly installed or grounded electrical attachments.The zinc rods must be inspected every 50 service hours and replaced when they have deteriorated.The location and number of zinc rods depends on the individual engine and the engine's attachments. Zinc rods are located in: the heat exchanger bonnet, the aftercooler lines, the raw/sea water heat exchanger bonnet, the raw/sea water pump, and the raw/sea water lines.Inspect
1. Remove all the zinc rod assemblies. The assembly plugs are painted red for easy identification. 2. Tap the zinc rods lightly with a hammer. If the rod has deteriorated, or flakes when tapped, install a new zinc rod.Replace
1. Unscrew or drill the old rod from the plug. Clean the plug.2. Apply 9S-3263 Compound to the shoulder of a new rod. Apply the compound only to the shoulder of the rod. Install the rod into the plug.3. Coat the external threads of the plug with 5P-3413 Pipe Sealant. Install the zinc rod assembly. Refer to the Torque Specifications in this manual.
