New Mercury 175HP 3.0L Diesel Outboard Engine

The Mercury 175HP 3.0L Diesel Outboard Engine for sale is engineered to deliver exceptional performance for commercial patrol boats and light-duty applications. Equipped with an innovative two-stage direct-injection system, this engine uses a small charge of compressed air to finely atomize the diesel fuel, allowing for smoother ignition via spark and improved high RPM running quality. A glow plug complements the spark plug, ensuring reliable cold weather starts and idle stability. The onboard Propulsion Control Module (PCM) microprocessor further optimizes fuel and spark timing for consistent performance across the engine’s operating range. The SmartCraft® Engine Guardian provides real-time self-protection diagnostics and alerts for engine faults.
