When to Replace
Replace the bonding cable kit if inspection reveals any of the following:
- Broken or missing bonding straps
- Corroded or damaged cable terminals
- Frayed or deteriorated conductors
- Loose attachment points
- Poor electrical continuity between bonded components
- Physical damage during steering, transom, or sterndrive service
A failed bonding connection can leave individual metal components outside the drive’s corrosion-protection circuit, accelerating galvanic corrosion on unprotected parts.
Service Interval
Inspect bonding cables during any sterndrive, transom, or steering service that involves removal of bonded components. Replace immediately if any cable or terminal shows damage, corrosion, or loss of continuity. Follow Mercury MerCruiser service procedures for corrosion-protection and continuity testing after installation.
Installation Notes
- Clean all bonding attachment points to bare conductive metal as specified
- Remove corrosion from beneath cable terminals before installing
- Inspect related bonding plates and continuity hardware at the same time
- Verify all cable terminals are fully secured after installation
- Confirm electrical continuity through all bonded drive components after assembly
- Follow the applicable Mercury MerCruiser service manual for corrosion-protection and continuity testing steps
Parts Desk Insights
Bonding cables are one of the most overlooked items during sterndrive service because they have no moving parts and don’t affect how the drive operates mechanically. Their job is electrical: keeping separate sterndrive and transom components at the same electrical potential so the corrosion-protection system works as designed. The most common issue is customers ordering only one kit when their specific assembly calls for two or three — always check the quantity in the parts diagram for your drive serial number. If one bonding strap is damaged or corroded, it’s worth inspecting the entire continuity system at the same time.
Technical FAQ
Q: What does the bonding kit actually do?
A: It electrically connects separate metallic drive and transom components so they share the same corrosion-protection circuit. Without it, isolated metal parts can corrode significantly faster.
Q: How many kits do I need?
A: It depends on your specific drive assembly — some diagrams call for up to three 847062A1 kits. Check the parts diagram for your drive model and serial number for the exact quantity.
Q: Is this the same as an anode kit?
A: No. Anodes are sacrificial zinc or aluminum components. This is a bonding/continuity kit — it ensures all metal parts are electrically connected so the anodes can protect the entire system.
Q: Does this fit all Bravo drives?
A: It is used across several Bravo variants but fitment depends on the specific transom assembly, steering configuration, and drive serial number. Confirm against the Mercury parts diagram for your drive before ordering.
