Mercury Lower Units for Sale New & OEM Outboard Gearcases

At Hawkeye Marine, we know a failing lower unit can sideline your season—grinding gears, water intrusion, or lost thrust from saltwater wear. That's why our collection of new and remanufactured Mercury lower units (plus select Yamaha and Johnson/Evinrude options) delivers factory-fresh reliability at a fraction of full OEM cost. Sourced from certified rebuilders like US Boatworks and PerfProTech, every gearcase undergoes rigorous testing: sandblasted housings, new seals/bearings, and OEM gears for smooth 1.75-2.25:1 ratios. Compatible with 2-stroke/4-stroke models from 40HP BigFoot to 300HP Verado, these units restore torque, reduce vibration, and prevent costly upper-engine damage—backed by 12-24 month warranties.

Why Choose Hawkeye's Lower Units?

  • OEM-Quality Rebuilds: Reman units use genuine Mercury/Yamaha/Evinrude parts—hot-tanked, machined, and pressure-tested for leak-free operation in harsh marine environments.
  • New vs. Reman Savings: Brand-new Mercury gearcases for peak specs; reman for eco-smart, budget-friendly upgrades (up to 50% less than new).
  • Easy Fit & Support: Pre-assembled for bolt-on installs; match by serial number with our fitment guide—free tech advice for props, shafts, and seals.

Featured Units in This Collection:

  • Mercury Focus: Reman V6 200-250HP (1.75:1, 25" shaft) for OptiMax/DFI; New 3.0L Verado L/XL for 175-225HP—RH/LH rotation options.
