Genuine Quicksilver Mercury Twin Engine Lower Unit Gear Lube Service Kit Complete Maintenance Bundle for Outboards, I/O, Verado, Optimax, BlackMax, Bravo I/II/III, XR Racing, SportMaster, TorqueMaster & More!

Keep your twin Mercury setup (outboard or sterndrive) protected and performing at peak with this brand-new, all-in-one lower unit gear lube change kit from Quicksilver—Mercury's official premium parts line. This kit covers the essential gear lube flush and refill for TWO engines/drives (perfect for twin-rig center consoles, catamarans, or performance boats in Fort Lauderdale's saltwater playground), helping prevent corrosion, water intrusion, bearing wear, and gear damage in high-load or high-speed conditions.

Why this kit is a smart choice:

• Genuine Quicksilver High-Performance SAE 90 Gear Lube outperforms standard oils with marine-specific additives for extreme pressure protection, shear resistance, and corrosion defense—ideal for high-HP applications like Verado, Optimax, Bravo drives, and racing setups.
• Includes a convenient Quicksilver gear lube pump for mess-free filling (threads into the lower unit drain plug—fits most 3/8"-16 plugs; adapter included for metric).
• Fresh lube + new gaskets every service ensures leak-free seals and extends lower unit life—DIY-friendly to save big vs. dealer service.
• Broad compatibility across Mercury/Mercruiser models: outboards (2-stroke/4-stroke), I/O, inboards, Verado supercharged, Optimax DFI, BlackMax, Bravo I/II/III, XR/SportMaster/TorqueMaster racing drives, and more.

Kit Includes (Genuine Quicksilver/Mercury Parts – For TWO Lower Units/Engines):

• 2 × Quarts Quicksilver High-Performance SAE 90 Gear Lube # 858064Q01 (marine-grade protection; ample for most twin setups—typical capacities: ~1-2 quarts per Verado/Optimax outboard lower unit, ~2.5-3 quarts per Bravo drive; fill from bottom until overflow at top vent)
• 1 × Quicksilver Gear Lube Pump # 8M0072133 (fits quart/liter bottles; quick, clean pumping for easy refills)
• 4 × Lower Unit Fill/Drain Plug Seals / Gaskets # 830749 (rubber-coated stainless steel washers—replace every service for reliable sealing; prevents leaks)

Brand New in Original Packaging – Never Opened! Quicksilver makes lower unit maintenance straightforward and reliable—great for local boaters doing annual or 100-hour services on twin rigs.

Important Fitment & Usage Notes:

• Fits most Mercury outboards (Verado L4/L6, Optimax, BlackMax, 2-stroke/4-stroke), Mercruiser I/O/inboards, and drives (Bravo I/II/III, XR, SportMaster, TorqueMaster, etc.) requiring SAE 90 high-performance gear lube.
• Always confirm exact gearcase capacity and lube spec with your owner's manual or engine/drive serial number (e.g., Verado ~32-34 oz per unit; Bravo ~2.5-3 quarts). Pump from bottom drain to top vent until clean lube flows out.
• If unsure about your model/serial or plug type (3/8"-16 standard; metric may need extra adapter), message me with details for quick verification.
• Shipping note: Continental U.S. only—no international, PR, HI, AK, or territories (per policy).
