Description

At the heart of the Piranha 9.9 HP lies a high-displacement 181 cc single-cylinder 4-stroke SOHC engine that delivers steady, usable power through the 5 500–6 000 rpm range. Its overhead-camshaft design ensures precise valve timing and reduced friction, producing responsive acceleration and reliable torque even under heavy load. A finely tuned carburettor optimises the air-fuel mix for maximum combustion efficiency, resulting in exceptionally low fuel consumption. Despite its compact size, the Piranha’s torque curve rivals that of twin-cylinder engines in its class, giving it strong low-speed thrust and confident planing ability for small boats.

The Piranha 9.9 HP is built around a reinforced aluminium block with a simple yet robust design that emphasises reliability and longevity. The Long Shaft (L) configuration provides greater propeller immersion and smoother power transfer on deeper-draft hulls or sailing auxiliaries. Its water-cooling system with pump-forced circulation keeps operating temperatures consistent, protecting internal components during prolonged use. All exposed metal parts are treated with Selva’s anti-corrosion marine coating, ensuring lasting durability in harsh saltwater conditions. Despite its sturdy build, the compact dimensions and light weight make it one of the most portable engines in its power range easy to lift, stow, or transfer between boats.

Manual starting is quick and effortless thanks to Selva’s recoil-assist system and low-compression design. The twist-grip tiller provides responsive throttle control and smooth steering, while vibration-dampening engine mounts reduce noise and fatigue during operation. Maintenance access is straightforward, with easily reachable oil fill points, fuel filters, and spark plugs for quick servicing. The Piranha 9.9 HP combines convenience with capability, offering boaters the simplicity of a small engine and the performance of a much larger one, perfect for those who value practicality without compromise.
