90-806534940 CORROSION PROTECTION - 7-7

Low Readings

Cause 1. 2. Loss of continuity between drive unit components and negative (-) battery terminal. Shore power green safety grounding lead not isolated from the power package ground (on boats equipped with shore power). Underwater metal parts on the drive unit and/or boat are unpainted or the paint is in poor condition. The boat has more exposed metal than the anodes and/or Mercathode system can protect. Anodes painted. 1. Remedy Ensure that continuity devices are not missing or damaged and that connections are clean and tight. Disconnect shore power and notice if reading increases. If so, install a Quicksilver Isolator 76664A3 or an isolation transformer. Prime and paint underwater metal parts. This will reduce the load on the anodes and/or Mercathode system.

4. 5. 6. 7.

Remove paint or replace anodes. Clean anode mounting surface or replace anodes if they have oxidized. Replace anodes if eroded 50% or more. Avoid any electrical interconnection between the Mercruiser product, Anodic Blocks, or Mercathode system and the paint by allowing a minimum of 1-1/2 in. (40 mm) of UNPAINTED area around these items on the transom of the boat. Remove paint. Reinstall the plastic caps.
The anodes are improperly grounded or inactive. 5. Anodes consumed (no longer protect). Drive unit and/or boat bottom painted with antifouling pant containing copper or tin. 6. 7.
Mercathode reference electrode or anode painted. Anodic heads used instead of plastic caps.
10. No power to Mercathode controller.
10. Connect the positive (+) volt meter lead (set on 0-20 volt scale) to the positive (+) controller terminal and the negative () volt meter lead to the negative () terminal. The meter should indicate battery voltage. Check for a blown fuse (if so equipped) on the starboard Mercathode system. Clean the connection or repair wiring as required. 11. Clean and/or tighten the connection. Repair the wiring.
11. Poor connection between reference electrode lead (brown) or anode lead (orange) and Mercathode controller.
7-8 - CORROSION PROTECTION 90-806534940

Low Readings (continued)

Cause 12. Faulty Mercathode reference electrode. Remedy 12. Disconnect the reference electrode lead (brown) from the controller R terminal. Connect the lead to the positive (+) terminal of a digital multi meter (set on 0-2000 millivolt scale). Connect the negative () meter lead to the negative () battery terminal. Note the meter reading; then repeat the test using a Mercathode Reference Electrode Tester 76675A1. You should obtain the same reading in both cases. If not, replace the reference electrode. 13. With anode and reference electrode leads connected to the controller, connect the jumper wire between R and negative (-) terminals on the controller. Connect the positive (+) lead of the volt meter (set on 0-20 scale) to A terminal on the controller. Connect the negative (-) meter lead to the negative (-) controller terminal. Reading should be as follows: D Freshwater Areas Electrodes Mounted on boat transom: 7.5 - 10.5 Mllivolts Electorde mounted on bottom transom assembly: 6.2 - 11.8 Millivolts D Saltwater Areas Electrodes mounted on Boat transom: 8.8 - 10.5 Millivolts Electrode Mounted on bottom of transom assembly: 7.5 - 11.8 Millivolts If the reading is low, replace the controller. 14. Install additional anodes or Mercathode system 88334A2. If the unit is already equipped with a Mercathode system, a second system may be required.

13. Faulty Mercathode Controller.
14. Additional corrosion protection required. Boats which are equipped with a sizable amount of underwater metal (stainless steel prop, after planes, etc.), or that are moored in an area with warm or rapid flowing water, may require additional protection.
90-806534940 CORROSION PROTECTION - 7-9

High Reading

Cause 1. Stray current corrosion. If an electrical current 1. flowing along a metal conductor leaves the metal for a water path, it will cause ionization of the metal, and an area of rapid corrosion. Poor connection between Mercathode reference electrode lead (brown) and R terminal on controller. Faulty Mercathode reference electrode. 2. Remedy Observe the reading while disconnecting the electrical components one at a time until you eliminate the high reading. Correct the course of stray current. Clean and /or tighten connection. Repair wiring as required. Disconnect the reference electrode lead (brown) from R terminal on the controller. Connect the lead to the positive (+) terminal of a digital multi-meter (set on 0-2000 millivolt scale). Connect the negative (-) meter lead to the negative (-) battery terminal. Note the meter reading; then, repeat the test using Mercathode Reference Electrode Tester 76675A1. Both tools should produce the same reading. If not, replace the reference electrode. Replace the controller.
Faulty Mercathode controller.
7-10 - CORROSION PROTECTION 90-806534940
Normal Reading But Corrosion is Evident
Corrosion on the entire drive unit Cause The drive unit is raised so fat that the sacrificial anodic trim tab is out of the water. Remedy Leave the drive unit in the In/Down position when the boat is moored to ensure the trim tab is in the water, providing protection.
Corrosion problem developed after refinishing the drive unit Cause A steel wire brush was used to clean the aluminum casting. Steel particles became entrapped and set up a small galvanic cell. Paint blistering on drive unit Cause Battery charger, which uses 110 volt shore power, improperly connected to the battery. Trim cylinder corroding Cause Continuity lost between trim cylinder and drive unit. Remedy Install proper continuity devices. Remedy Ensure the charger is connected correctly. Remedy Use only a nylon or bristle brush.
Only one or two components corroding (bellhousing, gimbal ring, etc) Cause Continuity lost between drive unit and components. Corrosion in the exhaust outlet area Cause Exhaust gas deposits accumulating on the drive exterior can result in paint blistering and corrosion. Remedy Remove deposits with marine or automotive wax. Remedy If not already done, install Continuity Circuit Kit 99940A1.

Corrosion occurs after the unit is removed from the water Cause Salt crystals remaining on the surface of the drive components combine with high humidity to cause electrolyte formation, which results in corrosion. Remedy Wash drive exterior and flush drive interior with fresh water.
90-806534940 CORROSION PROTECTION - 7-11
Corrosion between surfaces Cause Salt buildup between surfaces. Remedy Protect mating parts with Quicksilver Special Lubricant 101 (92-13872A1), Quicksilver 2-4-C Marine Lubricant (92-825407A2), or Perfect Seal (92-34227-1).
Aluminum corroding in lubricated areas Cause Graphite in the lubricant. Remedy Never use lubricants containing graphite, because they accelerate corrosion. Use specially formulated Quicksilver marine lubricants.
Stainless steel components corroding Cause Foreign matter (fishing line, marine growth, etc.) covering the steel and starving it of oxygen. This causes a breakdown of the protective oxide film and subsequent corrosion (known as oxygen.starvation corrosion). burying stainless steel in sand or silt also can cause this problem. Stainless steel propeller corroding Cause Continuity lost between propeller and propeller shaft. Remedy Clean the mating surfaces on the propeller, propeller shaft, and attaching parts. If applicable, install a continuity washer. Remedy Remove foreign matter and prevent surfaces from being covered by sand or silt.
Paint blistering - the metal under the blistered paint is not pitted Cause The surface was not properly prepared before paint was applied. Remedy Sand the surface down to bare metal, prime and repaint with Quicksilver Spray Paint.
