      Mercury 20 HP EFI 4 Stroke Outboard Parts

      Long considered one of the best in the business, the Mercury 20hp 4 stroke engine has a lot going for it. To begin, it is easy to install, as well as to operate. In fact, it is said that a novice can do it. That’s because of its reliable starting, low vibration, and instant throttle response. Of course, all these great features only work start after start, and season after season, if the Mercury 20hp four stroke is routinely maintained. The second most important part of any boat is the engine. So for optimal performance and a long service life, buy your replacement Mercury 20hp 4 stroke partsfrom Wholesale Marine.
