Your cart is empty.Engineered to provide maximum protection for sterndrive and Outboard lower units. Exclusive formula is engineered to provide extended gear life in extreme conditions including high-speed and high-horsepower applications. Extensively tested to provide excellent protection against corrosion and excessive wear. Specifically formulated to help prevent failures due to water entering the gear housing. Extreme pressure synthetic additives protect gears from metal to metal contact. Since no industry-wide standards exist concerning marine gear oils, it is essential to use products such as Mercury high-performance gear Lube which has been specifically designed and tested for marine applications. Note: do not mix with Mercury premium gear Lube. Provides warranty protection for all Mercury mercruiser sterndrive and Mercury, Mariner and force Outboard lower units. Mercury recommend the gear Lube be changed at least once per year (prior to storage) or every 100 hours of operation. See your owner's manual for specific recommendations.

This product is OEM Gear lube for Mercury outboard motors. Works great and the price was good.

Good product but deceptive picture. If you don't read the description carefully, it looks like you're getting two quarts in instead of one.

Why if you're only selling this product as one quart do they show 2 quarts. It's very easy to see a picture of two quarts and not read the text which says 1 quart. Think that's deceptive. Also, when I received my one quart.. it did not have a cap on it. If the very thin membrane had been punctured it would have been a real mess. So what happened to the cap and what kind of person would put a quart of oil in a box without a cap on it?

I do not know enough about lubricants to tell anything. It arrived well, and I added it, no problem. That is all I know.

So expensive and Mercury demands it but I feel there is a reason for using manufacturer recommended products

Great price, fast shipping. I'll be buying again. I change gear oil after every 25 hours. Cheap insurance for an expensive and necessary component of every boat.

I use this oil as I hope it gives me the best life and reliability for my outdrive. Can't go wrong with the manufacturer's brand, right? It's also blue so it looks pretty in the level monitor.
