Yamaha 150, 175, 200HP V6 Spanner-Nut Style Lower Unit Years 1988-2012

These are remanufactured outboard lower units (gearcases) for Yamaha 150, 175, and 200HP V6 2-stroke engines from 1988 to 2012. Rebuilt with all new bearings, seals, gears, and other components—including updated parts—these units often exceed original OEM reliability and performance.

Key Features and Specs:

• Design: Spanner-nut style bearing carrier (classic retention method for these 1988-2012 V6 models; differs from later bolt-in carrier designs—verify your existing unit for compatibility).
• Propeller Shaft: Typically 15 splines (standard for Yamaha V6 150-200HP models in this range).
• Drive Shaft & Water Pump: Not included—reuse your existing components (compatible with spanner-nut setups). Contact us for replacements if needed.
• Warranty: Includes a 2-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 $100.

Important Selection Tip: To ensure perfect fitment (shaft length, rotation—standard or counter-rotating—gear ratio, and model specifics like 3.1L/3.3L variants), please provide the serial number and model number from your motor's transom bracket. This is essential for matching these spanner-nut style V6 gearcases accurately.

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