Honda BF40D4LHA Outboard - 20" Shaft Electric Start Tiller Silver. Overview. The BF40D4LHA marks the entry point into Honda's higher mid-range outboards, delivering a true 40 HP with the smooth, refined character the brand is known for. With a 20" shaft, this model is designed for long-transom boats that need more authority without stepping into large-engine territory.. This configuration uses electric start and tiller steering, making it a strong option for skiffs, utility boats, and larger tiller-steered fishing boats that benefit from direct control. The added horsepower is immediately noticeable-boats plane faster, carry heavier loads more comfortably, and maintain speed with less throttle input.. Despite the power increase, the BF40 remains controlled and predictable. Idle is stable, throttle response is smooth, and vibration is kept in check, which makes it comfortable for long days on the water. It's a practical step up for boaters who have outgrown smaller engines.. Key Feature
