Honda Marine debuts three new 4-stroke engines

Honda Marine has introduced the new BF4 and BF6 4-stroke outboards, along with a redesigned BF5 model.

The 127cc 4-stroke, single cylinder engines offer boaters the choice of four horsepower (BF4), five horsepower (BF5) or six horsepower (BF6). All three new engines are available with either a short (15 inch/38 cm) or long (20 inch/51 cm) shaft.

“The new Honda BF4, BF5 and BF6 engines are easy to start, easy to stop and easy to carry. The new four-stroke Honda Marine engines are best-in-class performers. They are the right size for the right purpose,” said Mark DiPietro, senior manager, Honda Marine. “The new Honda BF4, BF5 and BF6 marine engines feature a new internal fuel tank and new motor mounts to run quietly and smoothly, while delivering the longest continuous running time.”

Honda is emphasizing four main features of the new engines, portability, performance, reliability and comfort.

  • Portability: A combination of light weight (roughly 60 pounds) and new carrying handle design make the Honda BF4, BF5 and BF6 marine engines easy to transport and store. The tiller handle fully folds out of the way, making storage options even more convenient.
  • Performance: The engines integrate a 1.5-liter, large capacity internal fuel tank which delivers the longest continuous running time in their class—more than 40 minutes at wide open throttle. In addition, the Honda BF5 and BF6 4-stroke engines can be connected to an external fuel tank for longer journeys. Consumers have the choice of an additional three different propeller options for the style that best fits their boating needs.
  • Reliability: Honda Marine’s new BF4, BF5 and BF6 models share the same one-cylinder, 127 cubic centimeter engine block and benefit from Honda’s 4-stroke engine technology expertise. In case of an oil pressure drop, a new, low oil alert system will automatically limit the engine speed to 2,300 rpm, helping to protect the engine and providing boaters peace of mind.
  • Comfort: The new Honda BF4, BF5 and BF6 portable engines feature a host of new technologies and feature:
    • A new decompression mechanism helps make all three new Honda Marine engines easy to pull start, regardless of the engine temperature. The decompression mechanism opens the exhaust valve during the starting process, which makes the engines easy to start.
    • One-push stop switch is a segment-first, and serves to shut down the engine with no chance of the engine re-starting; (no need to hold a button or switch until the engine stops completely).
    • The Honda Marine BF4, BF5 and BF6 portable engines feature redesigned rubber motor mounts that reduce vibration in all rpm ranges and reduce engine noise, offering comfortable cruising
    • The BF4, BF5 and BF6 are available with an optional charging system with a capacity of  6 Amps at 12 Volts to power consumer demands for electronic devices on board
