I use 80 weight gear oil.
Most outboard manufacturers recommend a good quality 10W-30 motor oil for use in colder climates.
any good quality two stoke oil including outboard motor oil
The Johnson J90PLSS outboard motor typically uses a mixture of gasoline and 2-stroke oil. The recommended fuel is unleaded gasoline with a minimum octane rating of 87, mixed with 50:1 ratio of 2-stroke oil. Always refer to the owner's manual for specific fuel requirements and recommendations.

The recommended spark plug for a 1992 model, 200hp Mercury 2 stroke carbureted outboard, is an NGK BU8H. This is a perma-gap type plug, so no gap setting is required.
No, you should not use 2-stroke lawn oil in your outboard motor unless it is specifically designed for that purpose. Outboard motors typically require a different type of oil formulated for marine use, which provides better lubrication and protection against the harsh conditions of saltwater or freshwater environments. Using the wrong oil can lead to engine damage and decreased performance. Always consult your owner's manual for the recommended oil type.
A 2.5 Mercury outboard motor typically uses a mixture of unleaded gasoline and two-stroke engine oil, usually in a 50:1 ratio. It's essential to use a high-quality oil specifically designed for two-stroke engines to ensure optimal performance and engine longevity. Always check the owner's manual for specific fuel recommendations and mixing instructions.
2 stroke-NOT outboard, but the same type such as used in chainsaws
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.
