  • 360 APX Racing Outboard

    360 APX Racing Outboard

    Mercury

    Please click to contact us if you are interested in this product.

    The Mercury Racing 360 APX is a potent competition outboard designed specifically to power Formula 1 tunnel boats in the premier class of the UIM F1H2O World Championship. The 360 APX is tuned to deliver amazing torque from a durable, low-emissions four-stroke V8 powerhead that sets a new benchmark for circuit-racing performance.

    A 4.6-liter V8 powerhead is naturally aspirated and features deep-breathing dual overhead cam/four-valve architecture with a short-runner intake manifold mated to a cold-air induction system. An 11:1 compression ratio boosts torque output while the 7000 RPM redline extends the power curve. A dynamic oil pickup system is designed to maintain critical engine oil pressure under high-G loads. A cut-down flywheel, deleted balance shaft and carbon fiber top cowl optimize weight.

    To align with the sustainability initiatives of the UIM and F1H2O organizations, this engine offers 90% lower exhaust emissions than current two-stroke racing engines.
