A Mercury 400 HP outboard means you're the kind of boat owner who appreciates a lot of power. So why would you want to sacrifice even one HP of that power? You paid for 400 HP and dammit you expect 400 HP from your outboard. But if you neglect servicing your outboard you'll be losing some of those precious HP from your motor, which is precisely what you don't want. Worn parts that should be replaced can sap power from an engine, so stay on top of the regular maintenance schedule and make sure you're replacing old and damaged parts as soon as possible. For the best results when servicing or repairing your motor always use genuine Mercury 400 HP outboard parts. With OEM Mercury Marine parts you get the build quality and longevity that aftermarket parts can't live up to. Hey, you want 400 HP right? So fit genuine Mercury outboard motor parts from Boats.net and you'll get them. You can also search for Mercury outboard parts by year.
