These are remanufactured outboard lower units (gearcases) for Yamaha F225, F250, and F300 4.2L V6 4-stroke engines from 2010 to 2024. Rebuilt with all new bearings, seals, gears, and other components—including updated parts for enhanced durability—these units often outperform original OEM quality.
Key Features and Specs:
- Compatibility: Fits F225, F250, F300 (including offshore and DEC models). Propeller shaft typically features 17 splines (standard for Yamaha 4.2L V6 4-strokes in this range).
- Drive Shaft & Water Pump: Not included—reuse your existing components (snap-in design on these models). If replacement needed, contact us for compatible parts.
- Warranty: Includes a 1-year manufacturer warranty. A 12-month extended warranty is available for an additional $540.
- Core Policy: If returning a core (your old lower unit), credit is determined by condition inspection. Maximum core value for this lower unit is $200.
Important Selection Tip: To ensure exact match (shaft length, rotation—standard or counter-rotating—gear ratio, and model specifics like mechanical vs. DEC), please provide the serial number and model number from your motor's transom bracket. This is essential for Yamaha 4.2L compatibility to avoid fitment issues.
Availability: These units are normally not stocked in-store and ship directly from the manufacturer. Contact us for current pricing, stock, lead times, core details, and any add-ons (extended warranty, drive shaft, etc.).
