At -50 degrees Celsius, mercury is in a solid state. Mercury typically freezes at approximately -38.83 degrees Celsius, so at -50 degrees, it would be well below its freezing point, resulting in a solid form. The solid mercury would appear as a shiny, metallic substance, retaining its characteristic high density and metallic luster.

The Johnson outboard model 6R75R with serial number J4168082 is typically from the year 1975. Johnson outboards used a system where the first digit of the serial number often indicated the year of manufacture, and in this case, the "4" in the serial number suggests it was produced in that year.

To determine the year of a 6HP Mercury outboard motor with the serial number 34028830C2, you can refer to Mercury's serial number lookup charts or contact a Mercury dealer. Typically, the first two digits of the serial number indicate the year of manufacture. In this case, the number suggests it was likely produced in the early 2000s, but for precise identification, checking with official resources is recommended.

The bearing number for a 55 kW motor can vary depending on the motor's design, manufacturer, and specific application. Commonly used bearings for such motors can include types like 6205 or 6305, but it's essential to refer to the motor's technical specifications or manufacturer's documentation for the exact bearing number. Always ensure that the chosen bearing meets the load and speed requirements of the motor.

A 50:1 gas and oil mixture refers to the ratio of gasoline to two-stroke engine oil used for fueling two-stroke engines, such as those found in chainsaws, lawnmowers, and dirt bikes. In this mixture, 50 parts gasoline are combined with 1 part oil, typically resulting in a mixture of about 2% oil. This specific ratio ensures proper lubrication of the engine components, helping to prevent wear and maintain performance. It's important to follow the manufacturer's recommendations for the correct fuel mixture ratio to avoid engine damage.

Tecumseh engines are small, air-cooled engines commonly used in outdoor power equipment like lawn mowers, snow blowers, and generators. They range in horsepower (hp) from about 3 to over 10 hp, with various models designed for specific applications.
