The characteristics and brand-specific differences of small, portable 4-stroke outboards are unfortunately rarely weighed. However, with the Honda models BF4, BF5 and BF6, there is an exceptional amount of reason for comparison - that's how civilized and easy-to-use machines in their class are now.
The Honda BF4, together with its big brothers BF5 and BF6, creates a new reference in terms of comfort of use. With these machines, the lightness of starting, quiet operation and vibration-free operation have been taken to an unprecedented level.
The semi-compression combined with the advanced starter rope mechanism guarantees that starting the engine requires no more than thought, no matter what the weather and temperature. Even the youngest in the family can easily start this engine!
Silence. Despite the compact and easily portable structure of the motor, the low sound level during operation is a new experience for the user with these motors. A feature that really matters to the user, with the engine running next to the ear.
Economy. The new BF4, BF5 and BF6 are equipped with a convenient 1.5-liter fixed fuel tank, which, considering the fuel economy of these machines, needs to be refueled less often than you might imagine.
Performance. With a displacement of 127 cm³, the 4-stroke engine is torquey and rev-sensitive. In addition, a wide selection of propellers guarantees customization even for special needs and with heavy boats in mind. Both the traditional short stroke (15" / 38 cm) and the long stroke BF6 engine (20" / 51 cm) are available in stroke lengths.
Reliability. You shouldn't play with engine reliability on the water. For this reason, many have already chosen Honda in the past. The new engines also have an oil pressure indicator and an oil monitor just in case, which automatically limits the revolutions to 2,300 rpm when the oil pressure drops. As usual, the engine is covered by Honda's 5-year warranty.
