New Range of Honda Engines
Honda have totally redesigned their flagship outboard motor range. Now the BF175, BF200, BF225 and BF250 will all be based on the 3.6L V6 engine block that previously only the BF250 used. This is a logical move that will not only slightly increase the capacity for three of them, but also involves a host of improved universal features. All engines will feature multiple rigging options, including Honda’s Intelligent Shift and Throttle system, which makes multiple engine harmonisation and control an easy one-lever affair. There will also be the option of old-school mechanical controls – essential for those wanting to repower older boats. In keeping with the latest technology trends, there will be a new user interface and various colour engine displays.
All four outboards debut the new Honda Progressive V form, with aerodynamic lines and an emphasised ‘V’ with centre grille and chrome detailing. The new design also provides better protection from both water entering the engine and from paint chips and scrapes. The outboards are equipped with a three-latch lock and seal system and two inverted grip points that make the cover easy to remove and carry – an important and often overlooked aspect for an engine that lives on the water. To enhance performance and provide better protection from water intrusion, the new cowling incorporates a dual-channel, indirect-air-circuit induction system that improves airflow while helping funnel moisture away from the throttle body. This is a feature that is becoming more popular with modern outboard engines, as cooler dry air provides more torque, among other things. The undercase design has been streamlined to incorporate three pieces (instead of seven on the previous model), along with a heavy protective rubber edge at the base of the cowling, further protecting against outside elements and increasing durability. A new rear utility cover on the cowling features a design consistent with that of the Honda BF115hp – BF150hp outboards.
These new engines incorporate more than just cosmetic changes to their appearance. They also feature a number of enhancements for improved reliability and ease of maintenance. Corrosion resistance is improved with a new coating on the surface of the engine hardware that utilises a chemically treated, zinc-nickel plating with a high corrosion-resistant top coat. In addition, a number of components, including the oil pan, thermostat cover, upper mount cover and prop shaft holder, use a higher corrosion-resistant material, resulting in a more durable engine and gear case. Finally, the number of anodes on the engine block has been increased from two to four.
Routine maintenance has been improved for activities such as oil and filter changes, courtesy of a larger-diameter dipstick tube, the integration of a water separator and fuel strainer, and relocation of the high-pressure filter for easier access. For example, changing a high-pressure fuel filter on any of the new V6 motors can now take as little as 5 minutes, compared to the 60 minutes on existing models.
These new engines will be available in the autumn of 2018. Price to be announced.
