The plug gap for the 1990 model, 100 hp Mercury outboard is .040 in.
The weight for a Mariner 100 hp would be the same as the Mercury at 315 lbs.
The 100 hp firing order is 1-3-4-2.

What is the value of a good running 1972 100 HP Johnson out board motor
The 1975 year model, 100 hp Evinrude, requires a 50:1 fuel to oil ratio.
A 100hp outboard engine can typically propel a boat at speeds ranging from 25 to 45 miles per hour, depending on factors such as the boat's weight, hull design, and water conditions. Lighter, more streamlined boats may reach higher speeds, while heavier vessels may be slower. Additionally, the type of load and weather conditions can also influence overall performance.
The fuel oil mix for a 1979 100hp Evinrude outboard motor is typically a 50:1 ratio, which means you should mix 2.6 ounces of two-stroke oil per gallon of unleaded gasoline. It's important to use quality two-stroke oil designed for outboard motors to ensure optimal performance and engine longevity. Always refer to the owner's manual for specific recommendations and guidelines.
A 100 hp Evinrude outboard motor typically weighs around 350 to 400 pounds, depending on the specific model and year. This weight can vary slightly due to design changes or additional features. It's important to consult the manufacturer's specifications for the exact weight of a particular model.

The point at which the horsepower measurement is taken. A 100hp outboard engine may only deliver 87 horsepower to the propeller due to losses in the transmission and bearings. The engine horsepower is 100, but the shaft horsepower rating is 87 horsepower.
