Description

At the core of the Black Bass Big Foot Sail 8 HP lies Selva’s durable 165 cc single-cylinder 4-stroke SOHC engine, tuned for smooth torque delivery and efficient fuel use. Working within its 5 500–6 000 rpm operating range, it provides dependable thrust at low speeds, ideal for docking or maintaining steady course in light winds. The simple overhead-camshaft design minimises internal friction, ensuring quiet, vibration-free operation and long mechanical life. The combustion system has been refined to maximise power from minimal displacement, offering clean, economical performance that extends range and reduces refuelling stops.

Built around a corrosion-resistant aluminium alloy block, the Black Bass Sail 8 HP combines lightness with long-term strength. Its Big Foot transmission features an enlarged gear housing and propeller hub, optimised for high-thrust output. The Extra Long Shaft (XL) keeps the propeller fully submerged for better control on sailboats and deeper-draft hulls, maintaining bite and efficiency even when the vessel heels or pitches. The water-cooling system with pump-forced circulation maintains ideal temperatures during long operation, while Selva’s protective coatings guard against salt-water corrosion. Compact engine dimensions make it easy to mount or remove, even on narrow transoms or auxiliary brackets.

Manual starting is smooth and dependable thanks to Selva’s recoil-assist system, while low-vibration engine mounts keep running noise to a minimum. The twist-grip tiller offers responsive throttle control, and the unit’s light weight makes handling simple both on deck and during installation. The model can also be configured for remote control, giving skippers the convenience of helm-side operation. Five-position manual trim adjustment lets the user fine-tune engine angle for optimum performance and fuel economy. Compact, balanced, and remarkably quiet, the Black Bass Big Foot Sail is engineered for effortless operation and long-term comfort at sea. Reliable, portable, and purpose-built for sailboats, the Selva Black Bass Big Foot Sail 8HP 4-Stroke Outboard Engine (Extra Long Shaft) combines the control of a long-shaft drive with the simplicity and efficiency of a single-cylinder powerhead, making it one of the most trusted choices for auxiliary propulsion under sail.
