Description:

Hi-Performance Gear Lubricant – Synthetic Blend, 1 Quart / 946ml (18-9650-2)

Premium synthetic-blend gear lube for high-load marine drive systems.

This Hi-Performance Gear Lubricant is engineered to exceed the capabilities of standard OEM gear oils, delivering maximum protection for outboard and sterndrive lower units operating under heavy load or high-performance conditions. Its advanced synthetic-blend formula reduces friction, improves gear efficiency, and provides exceptional wear protection for gears, bearings, and all critical gearcase components.
Designed for both outboard and I/O applications, this GL-5-rated lubricant maintains film strength under extreme pressure while resisting foaming, breakdown, and water intrusion. It is a direct replacement for leading OEM gear lubricants, including Mercury/Quicksilver High-Performance Blend and Yamaha Yamalube gear oil.

Key Features
- Synthetic-blend marine formula reduces operating friction for improved performance
- Protects gears, bearings, and all key gearcase components
- Ideal for high-load and high-performance outboard and sterndrive applications
- Designed to exceed OEM high-performance gear lubricant standards
- GL-5 rated for extreme-pressure protection
- Direct replacement for Mercury (Quicksilver) Hi-Performance Blend and Yamaha Yamalube LUB-GEARL-11-00
- Shipping box quantity = 12

Questions & Answers

Question: Hi, I’m just researching the best gear oil for my Mercruiser Alpha Gen 2 Sterndrive which I’m just about ready to service. Sierra seems to be the best Synthetic Gear Lube for this job. My question is that this packaging seems to be totally different to the normal Sierra 18-9650-2 lube that I have seen and I’d hate to use an inferior product. Could you please explain why the packaging is different? Thank you Regards Graeme Todd

Hey Todd, its the same gear oil, just Sierra went through a refresh of their packaging to make it more modern with consistent branding across the board. No change to the gear oil.
