Powerful and Reliable 4-stroke Boat Engine for Demanding Boaters
Honda BF100AK1 LRTU is a premium outboard boat engine with 100 HP, combining the latest Honda technologies with the legendary reliability of the Japanese brand. This engine is ideal for medium to larger boats and offers an excellent balance of performance, consumption, and environmental friendliness.
Advanced Technologies for Unique Performance
VTEC (Variable Valve Timing and Lift Electronic Control)
Honda BF100 features the exclusive VTEC technology known from Honda cars. This technology automatically switches between two profiles - a less fuel-intensive profile at low speeds, and the highest performance at high speeds.
BLAST (Boosted Low Speed Torque)
The BLAST system dramatically improves acceleration at low speeds by advancing ignition timing one degree before the knock limit. This results in faster torque at low speeds and planing.
Lean Burn Control
This technology automatically adjusts the air-fuel mixture according to speed and load, allowing the engine to operate with up to 20% less fuel consumption at cruising speed compared to the competition.
Exceptional Fuel Efficiency
According to tests on the Alumacraft Voyageur 175 boat:
- Maximum Speed: 41 mph at 6,300 rpm
- Cruising Speed: 20.6 mph at 3,500 rpm, consuming 2.3 gal/hr (9.0 mpg)
- Medium Speed: 25.2 mph at 4,000 rpm, consuming 3.2 gal/hr (7.9 mpg)
- Higher Speed: 29.9 mph at 4,500 rpm, consuming 4.4 gal/hr (6.8 mpg)
