Honda BF115
We’ve Got The Power.
Take the joy of boating to the next level with the new BF115 – 150 series. We’ve reengineered and redesigned the 115 and 150, added the new BF140, and added upgrades and improvements that boost performance.
Available in Aquamarine Silver or Grand Prix White, the BF115, BF140, and BF150 all feature sleek, aerodynamic styling for a bold, new look. But good looks are just the beginning.
All three outboards are now available with Honda’s Intelligent Shift and Throttle (iST®) drive-by-wire system, for superb control and power.
Repositioned anodes and a new bolt coating boost corrosion resistance. The redesigned cowl provides easier spark plug access. Other redesigned and repositioned components include the trim and tilt unit, water separator, fuel filters, and an enlarged dipstick tube. Combined with enhanced diagnostic codes, these changes make maintenance easier than ever, and significantly reduce maintenance time.
The redesigned, reengineered Honda BF115, BF140, and BF150 deliver everything you want – and more.
