Suzuki placed a high priority on ergonomics and ease of operation when designing these 4-strokes. The engines have a slim, clean appearance with no awkward protrusions on which to catch lines or clothing. The tiller and controls are centrally positioned with the emergency stop switch incorporated into the handle itself and the clutch, start switch and LED displays located on the tiller support bracket. The decompression release makes for easy manual starting. Engine vibration is minimized by the use of thick anti-vibration mounts and other features include rev limiter to prevent over-revving when the engine is started in neutral and a delayed advance function which keeps the engine running evenly when decelerating quickly.
