Quality Remanufactured Lower Units
Welcome to Part 4 of our Gearcase Education Course! In the previous articles, we discussed OEM and Non-OEM lower units. Today, we’re diving into remanufactured or rebuilt gearcases—a cost-effective and environmentally friendly option that balances quality and affordability.

What Is a Remanufactured Gearcase?
A remanufactured or rebuilt gearcase starts with the original metal exterior shell of the unit. The outer case is cleaned, sanded, and repainted to restore its appearance. The worn-out internal components are then replaced with new parts, resulting in a gearcase that functions like new.
This process not only ensures the internal components are updated but also reduces environmental waste by recycling the outer shell.
Why Choose a Rebuilt Gearcase?
Remanufactured gearcases are a popular choice for many boaters because they combine quality and value. Here’s why this option stands out:
Cost Savings:
Remanufactured units are significantly more affordable than new OEM options.
Built by Experts:
Usually built by trained mechanics in the USA, ensuring high-quality assembly.
Internal Parts:
Rebuilt units should come with OEM internal parts for the best reliability and longevity. Choose your remanufacturer wisely and insure the you have the best possible product that won’t leave you stranded on the water.
Warranty Coverage:
Most units come with a one-year warranty (though warranty details may vary).
OEM Specifications:
Built to meet manufacturer standards, offering full compatibility and interchangeability with OEM drives.
Eco-Friendly:
Recycling the outer shell reduces landfill waste, and core charges encourage further recycling efforts.
Quick Shipping:
Many units are ready to ship within 24 hours.
Understanding Core Charges
Core charges are an essential part of the remanufacturing process. This refundable fee is added to your invoice and returned once your old gearcase core is sent back to the rebuilder.
Upon receipt, the rebuilder inspects your old unit to determine which parts, if any, are reusable. Refund amounts depend on the condition of the returned core. Be sure to check with your rebuilder for details about their specific core charge program.
