my manual says, sae 90 outboard motor grease, hope i helped
For the 80 hp Mercury, you may use any brand of gear oil that has been blended for use as an outboard motor gear lube. There are many brands available other than oem, and are specially formulated for outboard use.
The speed of a 12hp engine in mph depends on various factors such as the weight of the vehicle, the gear ratio, and the aerodynamics. Generally, a 12hp engine can propel a small vehicle like a go-kart or a lawnmower to speeds ranging from 20-40 mph. However, for a more accurate estimation, a specific vehicle and its characteristics would need to be considered.
The 1973 model, 7.5 hp Mercury outboard, requires 6.8 oz. of gear oil.
The 5 hp Mercury outboard requires no special type gear oil. General recommendation is for a GL-5 class lubricant, i.e. hypoid 90w. Most any of the oem, or aftermarket gear lubes, manufactured for outboard use, will work just fine.

For a 90hp Mercury two-stroke outboard, you should use a high-quality lower unit gear lube specifically designed for outboard motors. Mercury recommends using their own brand of gear lube, such as Mercury High-Performance Gear Lube or Quicksilver Gear Lube, which offer excellent protection against wear and corrosion. Always check the owner's manual for specific recommendations regarding viscosity and any additional requirements.

If the horsepower of your Mercury outboard lower unit is 75 and below, SAE 80W90 Gear Lube is recommended.

The gearcase assembly on an outboard engine is sealed, and draining is not needed. If however, the gear lube has not been changed in a while, during the water pump replacement is generally a good time to do so.
