Description
The DF15AS incorporates technology that’s genuinely unique in its class. Suzuki’s engineers completely redesigned fuel injection system components — including the high-pressure fuel pump, fuel cooler, vapor separator, and injectors — to be smaller and lighter than any previous system, making battery-less EFI possible in this horsepower class . The result is quicker, easier starts without the bulk and weight of a battery.
The Lean Burn Control System continuously monitors engine performance and operating conditions to predict fuel needs and deliver a leaner fuel-air mixture, resulting in significant fuel savings across the entire operating range . This isn’t marketing language — it’s a measurable advantage for boaters facing rising fuel costs.
The DF15AS also features decompression release for easy starts, a fresh water flushing port for simplified maintenance, and multi-layer corrosion protection designed specifically for saltwater environments
