Product Description

At the heart of the Swordfish 100XS lies Selva’s proven 2 670 cc DOHC 16-valve 4-stroke block, delivering a commanding 100 horsepower (73.6 kW) across a wide 5 000–6 000 rpm range. Its EFI system continuously adjusts fuel delivery for optimum combustion, ensuring instantaneous throttle response, clean acceleration, and exceptional economy. The single throttle body and long tuned plastic intakes maximise airflow efficiency, resulting in stronger mid-range torque and smoother power curves. A precision knock sensor further refines ignition timing, enhancing both performance and engine protection. This integration of electronic control and mechanical precision gives the Swordfish 100 XS effortless pull and quiet confidence at any speed.

The Swordfish 100XS Extra Long Shaft is designed for long-term endurance in demanding marine environments. Its corrosion-resistant aluminium block, reinforced lower unit, and advanced cooling system with pump-forced circulation ensure durability under heavy operation. The Extra Long Shaft (XL) configuration provides deep propeller immersion, making it ideal for larger hulls, sailboats, and deep-transom craft requiring stable thrust and improved directional control. Every surface is treated with Selva’s marine-grade multi-layer anti-corrosion coating, while the DOHC 16-valve configuration enhances mechanical efficiency and reduces wear. The result, an engine built not only for performance but for years of reliable service in saltwater conditions.

Starting is instantaneous and reliable with Selva’s EFI-assisted electronic ignition system. Operation is remarkably quiet, thanks to a perfectly balanced crankshaft, advanced intake silencing, and vibration-dampening mounts. The Swordfish’s Power Trim/Tilt function allows precise adjustment of the engine’s running angle for optimum lift, speed, and fuel efficiency. Maintenance is simple and accessible, with service points for oil, filters, and plugs positioned for easy reach. Combined with Selva’s drive-by-wire-ready electronic control interface, this model offers effortless handling and total user comfort.
