HONDA 2.3 HP BF2.3DHSCH Outboard Motor The best things come in small packages.  And that's especially true with Honda's BF2.3, one of the world's lightest four-stroke outboards. The BF2.3 is so light, it rivals many two-stroke 2HP engines and electric motors, without the battery! But just because it's lightweight doesn't mean we cut back on the power. The BF2.3 features 15% more power over its predecessor. Plus we added a 12% larger internal gas tank, which provides for about one hour of operation at wide open throttle. It's a technologically advanced design that gives you power and performance, without sacrificing portability
