Lastly, issues with the control mechanism, such as a faulty throttle or gear shifter, could also be at fault.

A 1 horsepower (hp) motor typically draws about 746 watts of power. To calculate the current it takes, you can use the formula ( I = \frac{P}{V} ), where ( I ) is the current in amperes, ( P ) is the power in watts, and ( V ) is the voltage. For example, at 120 volts, a 1 hp motor would draw approximately 6.2 amps, while at 240 volts, it would draw about 3.7 amps. The actual current may vary based on the motor's efficiency and the load it is under.

The fuel mixture for a 1977 Johnson Javelin 85 hp outboard typically requires a 50:1 ratio of gasoline to oil. This means mixing 2.6 ounces of two-stroke engine oil per gallon of gasoline.

An outboard motor water pump operates by drawing water from the body of water in which the boat is submerged. As the engine runs, the pump's impeller spins, creating a vacuum that pulls water into the pump housing. The impeller then forces the water through the cooling system, circulating it to cool the engine and expel excess water through the exhaust. This continuous flow prevents overheating and ensures the engine operates efficiently.
