Gearcase, Add Extended Warranty

These are brand new or remanufactured outboard lower units (gearcases) for Mercury V6 3.0L engines in the 200 DFI, 225, and 250 HP range from 1994 to 2018 (including DFI/Optimax models). Each unit is factory-new with full warranty coverage and includes a water pump for immediate installation.

Key Features and Specs:

  • Propeller Shaft: 15 splines (standard for Mercury 3.0L V6 200-250HP gearcases in this year range; compatible with most props for these models).
  • Water Pump: Included (not pre-installed—install during setup, add gear lube, and you're ready).
  • Drive Shaft: Not included—reuse your existing drive shaft (snaps in on these models). Contact us if a replacement is needed.
  • Warranty: Comes with a 1-year manufacturer warranty. A 12-month extended warranty is available for an additional $540.
  • Core Policy: No core charge required, and no core value/credit if an old unit is returned.

Important Selection Tip: To match the correct gearcase (shaft length, rotation—standard or counter-rotating—gear ratio often 1.75:1 or similar, and model specifics like DFI vs. Optimax), please provide the serial number and model number from your motor's transom bracket. This ensures perfect compatibility for these 3.0L V6 units.

Availability: These units are normally not stocked in-store and ship directly from the manufacturer. Contact us for current pricing, stock, lead times, and any add-ons (extended warranty, drive shaft, etc.).
