Section 6 • Electrical Systems

Zinc anodes require replacement about every six months, if the boat is operated in salt water. In fresh water, the zinc anodes can be replaced about once a year.

If the anodes deteriorate more rapidly than this, there is probably a stray current problem within the boat or at the slip or mooring.

If the anodes do not deteriorate, they are not protecting the other metallic parts of your boat. This can be caused by loose anodes or by low grade zinc or by not having a solid electrical contact between the anode and the metal it contacts, or by paint on the anodes.

If the anodes are deteriorating rapidly, or not at all, contact your dealer.

NOTICE

DO NOT PAINT BETWEEN THE ZINC AND THE METAL IT CONTACTS, AND DO NOT PAINT OVER THE ZINC.

3.Marine Electronic Cathodic Anti-corrosion System (Mercathode®)

The automatically controlled Cathodic Anti- Corrosion System for marine installation protects underwater metals from the effects of corrosion and electrolysis on stern drives. The system components are designed for marine service. DO NOT PAINT THE MERCATHODE® SYSTEM.

The anode and reference electrode are attached to the electrode assembly under each stern drive unit. The solid state controller is mounted within a plastic housing on the transom in the bilge.

Maintenance

The Mercathode® system must be tested to ensure adequate output. The test should be performed every 100 hours or annually. Contact your authorized Baja® dealer to arrange for this test. Refer to the engine operator's manual for more detailed information.

4.Electrical Systems

This owner’s manual contains electrical schematics and wiring harness illustrations for your boat. These electrical schematics were generated by electrical CAD designers at the engineering division for technical reference and service technicians. Baja® does not recommend that you attempt to work on the boat’s electrical system yourself. Instead, we recommend that you take your boat to your authorized Baja® dealer for service. Baja® reserves the right to change or update the electrical system on any model at any time without notice to the consumer and is NOT obligated to make any updates to units built prior to changes unless required by law.
