      Mercury 300 HP V8 Outboard Parts

      The Mercury 300 HP V8 engine is an outboard with a lot going for it. It offers mid-range power and a mastery of sharp turns, as it is equipped with a smooth gearbox and a responsive throttle. For most crafts it provides a top-end speed of about 73m/h at wide open throttle, and, as it is a Mercury, the 300 is dependable as well as durable.

      When your Mercury 300 HP V8 needs replacement parts, you can go about it one of two ways.
