Sierra 18-9650-7 96507 Hi Performance Gear Lube, 55 Gallon Drum Product Description
Upgrade your marine engine's lower unit with Sierra Hi-Performance Gear Lube, engineered for the demands of high-speed boating, racing, and heavy-load operations. This premium lubricant minimizes friction across gears, bearings, and gear case internals, delivering smoother operation and extended component life even under extreme conditions.
Standout Features for Superior Protection
- Advanced Friction Reduction: Specialized additives cling to metal surfaces, forming a tough protective film that slashes wear during peak loads.
- Extreme Pressure Formula: Handles intense torque and heat without breaking down, ideal for competitive outboards and inboard/outboard (I/O) drives.
- Superior Thermal Stability: Maintains viscosity across wide temperature swings, from icy starts to scorching summer runs.
- Water-Resistant Barrier: Repels moisture ingress, preventing corrosion and emulsification common in marine environments.
- 55-Gallon Drum Packaging: Bulk supply perfect for fleets, shops, or frequent maintenance pros seeking cost-effective, high-volume reliability.
Unlock Peak Performance and Longevity
In the world of high-performance boating, every second and mile counts. Sierra's formula outperforms standard gear lubes by resisting shear forces that degrade ordinary oils, ensuring your lower unit runs cooler, quieter, and stronger. Boaters report noticeable shifts in gear smoothness and reduced operating temperatures after switching, translating to fewer breakdowns and more time on the water.
Real-World Applications
Whether you're pushing a high-horsepower outboard to its limits in tournaments or hauling loads with an I/O sterndrive, this lube steps up. It's a go-to for offshore fishing pros, waterski pullers, and recreational racers who demand OEM-surpassing protection without compromise.
Pro Tips for Maximum Gear Lube Effectiveness
- Regular Inspections: Check lube color and level monthly—milky appearance signals water contamination, prompting an immediate change.
- Proper Warm-Up: Run the engine at idle for 5-10 minutes before full throttle to circulate lube evenly.
- Drain and Refill Routine: Every 100 hours or annually, whichever comes first, for optimal protection—use a pump for clean, efficient fills.
- Pair with Quality Seals: Inspect and replace lower unit seals during service to lock in performance.
- Storage Best Practices: Keep drums in a cool, dry spot away from direct sun to preserve additive integrity.
These habits not only amplify the lube's benefits but also catch issues early, saving you from costly gear repairs down the line.
