Outboard Motor 2 Stroke 15HP 6B4 factory
An outboard motor is an engine mounted on the outside of a boat, and a 2-stroke engine produces power in two strokes of the piston (rather than the four strokes of a 4-stroke engine). A 15HP outboard motor with a 2-stroke engine means that the engine produces 15 horsepower and operates using a 2-stroke cycle.
