GLOXTED Fused Wiring Harness for Mercury/Mariner 135HP–150HP (2011) — Direct-Fit Corrosion-Resistant

GLOXTED 8M0057698 is a direct-fit fused replacement wiring harness built to restore electrical reliability to Mercury 135HP/150HP and Mariner 150HP 2011 outboard engines.

When an aging or damaged harness causes intermittent power issues, blown circuits, or unreliable connections on your outboard motor, a precise, durable replacement matters. The GLOXTED 8M0057698 harness replicates the original routing and fused protection so you can reinstall quickly and get back on the water with confidence. It’s engineered for marine conditions with materials selected for corrosion resistance and long-term performance.

What does this fused harness replace and which engines is it compatible with?

This harness is manufactured to match the fit and function of part number 8M0057698 and is compatible with Mercury 135HP and 150HP outboards, plus Mariner 150HP 2011 models. It replaces worn, heat-damaged, or electrically unreliable factory harnesses to restore proper circuit protection and connectivity.

• Direct replacement for part number 8M0057698
• Fits Mercury 135HP and 150HP outboard engines
• Compatible with Mariner 150HP 2011 outboard models
• Designed to match original harness routing and connector types

How does the fused design improve electrical safety?

The integrated fuses protect individual circuits from overloads and help prevent wiring damage or component failure. By restoring the fuse points and proper conductor sizes, the harness reduces risk of electrical faults and simplifies diagnosis and future service.

• Pre-installed fuse locations for circuit protection
• Prevents overload damage to wires and components
• Helps maintain stable power delivery under load
• Makes troubleshooting and fuse replacement straightforward

Is installation straightforward and what tools are typically needed?

The harness is made for plug-and-play installation where connector types and routing mirror the original, minimizing modification. While many owners can install with basic hand tools, having a service manual and standard tool set ensures correct routing and secure connections.

• Intended for direct-fit installation with original connectors
• Basic tools usually suffice: screwdrivers, pliers, socket set
• Recommended: service manual for torque specs and routing diagrams
• No complex rewiring or splicing required when used as intended

What materials and construction features help it endure marine use?

Wire insulation and connector materials are selected for resistance to moisture, salt, and vibration common in marine environments. The harness construction prioritizes secure terminations and protective sleeving to reduce chafe and extend service life.

• Durable insulation resistant to abrasion and salt exposure
• Secure crimps and terminals for reliable conduction
• Protective sleeving and routing to minimize chafe
• Quality control to maintain consistent connector fit and function

Who is this for: The GLOXTED 8M0057698 harness is intended for boat owners, marine mechanics, and shops maintaining Mercury or Mariner outboards who need an accurate, rugged replacement for a failing factory harness. It’s particularly useful for anyone restoring electrical reliability on 135HP or 150HP Mercury engines or servicing Mariner 150HP 2011 units. If you want a ready-to-install harness that restores factory-style fused circuit protection and minimizes installation time, this part is a practical choice.
