Full details
This Quiksilver High Performance Gear Lube is designed for owners of Mercury Marine outboard motors and sterndrives above 75hp, offering superior protection against corrosion and wear. Its key benefit is the extreme pressure synthetic additives that prevent metal-to-metal contact in lower units. A potential caveat is that it's specifically formulated for certain Mercury applications, so verifying compatibility is essential.

What does 'extreme pressure synthetic additives' mean?
These additives create a strong protective film on gear surfaces, preventing metal-to-metal contact and reducing wear even under high loads and stress.
Can I use this lube in my sterndrive?
Yes, this lube is formulated for sterndrive applications above 75hp, in addition to outboard motors.
What are the previous and current Mercury part numbers for this product?
The previous manufacturer part number was 858064Q01, and the current manufacturer part number is 8M0222065.
How do I know if I need to change my lower unit gear oil?
It is generally recommended to change lower unit gear oil annually or every 100-200 hours of operation, or as specified in your engine's service manual. Look for signs of water contamination (milky oil) or metal particles in the old oil.
Troubleshooting
Difficulty pumping lube into the lower unit
Ensure the fill hole is clear of debris. Use a compatible gear lube pump and verify it is securely attached to the lube bottle.
Oil leaking from seals after refill
Check that drain and fill plugs were tightened correctly. If leaks persist, the seal may be compromised and require professional inspection.
Milky or foamy appearance of old lube
This indicates water contamination. Thoroughly drain the old lube and refill with fresh Quiksilver High Performance Gear Lube. Monitor for recurrence, which may signal a seal issue.

Setup, Compatibility & Care Instructions
Compatibility: This gear lube is specifically designed as a direct replacement for Mercury Marine part numbers 858064K01 and 8M0222065. It is intended for use in Mercury Marine outboard motor lower units and sterndrive applications rated above 75hp that require SAE 90 viscosity gear oil. Always consult your marine engine's service manual to confirm the correct lubricant specification before use.
Setup (Gear Oil Change):
- Ensure the boat is on a level surface.
- Locate and remove the lower drain and fill plugs on the lower unit.
- Using a gear lube pump, fill the lower unit from the bottom (fill) hole until the oil just begins to flow out of the top (vent) hole.
- Replace the vent plug, then remove the pump and replace the drain plug.
- Dispose of used oil responsibly.
Care: Store the gear lube in a cool, dry place away from direct sunlight. Keep the container tightly sealed to prevent contamination. Regular inspection of the gear oil during maintenance checks can help identify potential issues early.
