Mid 80s
A 18hp Mercury outboard, serial number 5955388 is a 1982 year model.
An 18 hp Evinrude outboard, model 18202 would be a 1972 year model.
18hp
The fuel mix is 24:1
The 18hp Johnson Seahorse model FD-16A outboard motor was manufactured in 1965. This model is part of the Johnson Seahorse series, which was popular during that era for its reliability and performance. If you need more specific information about its features or history, feel free to ask!
the 15hp murc is the best relay an 18hp and are cheap new i bought my 15hp murc with and 18hp relay and go it for $1800 brand new and runs the best i have ever seen and much faster and cheaper than Yamaha
The oil mixture for that motor is 1 pint of oil to 6 gallons of gas
The 1961 Johnson Sea Horse 18hp outboard motor typically requires a fuel mixture of 50:1, which means 2.5 ounces of 2-stroke oil per gallon of gasoline. It's important to use a high-quality 2-stroke oil designed for outboard motors to ensure proper lubrication and performance. Always refer to the owner's manual for specific recommendations and to verify the correct ratio for your engine model.
A 1957 Evinrude 18 hp weighs 85 pounds, so I would assume the Johnson 18 hp would be about the same, give or take a few pounds.
