Quicksilver Lower Shift Cable for MerCruiser MC-I/MR/Alpha One Gen II – 865436A02 OEM-fit, Corrosion-Resistant

Quicksilver 865436A02 (8M0176524) is a direct-fit lower shift cable built to replace worn or broken shift linkages on MerCruiser MC-I, MR, Alpha One and Alpha One Gen II sterndrives.

If your MerCruiser shift feels loose, stiff, or fails to engage gears, this lower shift cable provides a durable, OEM-spec replacement. Manufactured to match Mercury Marine specifications, the cable is engineered for reliable performance in harsh marine environments, operating smoothly at temperatures down to below 0°F. It’s intended as a full replacement part — shift cables are not serviceable — and installs easily using standard hand tools by reversing the removal steps.

Will this cable fit my MerCruiser sterndrive model?

Yes, the Quicksilver 865436A02 (also referenced as part number 8M0176524) is made to fit MerCruiser MC-I, MR, Alpha One and Alpha One Gen II sterndrives from 1978 and newer. Always confirm your drive model and year before ordering to ensure compatibility. If your drive uses a lower shift cable design consistent with these series, this part will match factory dimensions and attachment points.

• Cross-referenced with manufacturer part 8M0176524
• Designed to match OEM attachment and length specifications

How tough and weather-resistant is the cable?

This lower shift cable uses a layered construction that balances flexibility and strength for long-term use in marine conditions. It’s rated to perform at temperatures below 0°F and resists corrosion, abrasion, and the repeated flex of steering and shifting cycles. That makes it suitable for recreational and workboats that face variable weather and water exposure.

• Layered technology for smooth, consistent operation
• Built to resist saltwater corrosion and wear
• Operates reliably at sub-freezing temperatures

How difficult is installation and what tools do I need?

Installation is straightforward for anyone comfortable with basic mechanical tasks; the replacement is done by removing the old cable and installing the new one in reverse order. No specialized tools are required — common hand tools handle the clamps, fasteners, and linkage adjustments. Verify cable routing and secure all fittings before testing to ensure proper gear engagement.

• Remove old cable, install new cable in reverse order
• Uses common hand tools—wrenches, pliers, screwdrivers
• Adjust and test shift linkage after installation

Who is this for: This Quicksilver lower shift cable is intended for boat owners, marine technicians, and DIY mechanics maintaining MerCruiser-powered boats who need a reliable, OEM-spec replacement. It’s a practical choice if you’re restoring older drives, replacing a frayed or seized cable, or upgrading degraded shift components to restore crisp gear engagement. Since shift cables cannot be repaired, replacing a damaged unit with this Quicksilver part keeps shifting safe and predictable on the water.
