Product Description

The Sea Bass 6HP harnesses a finely tuned 118 cc 4-stroke overhead-valve engine designed to balance low weight with high efficiency. The advanced intake geometry increases airflow and torque output across the 5 000–5 500 rpm band, giving the engine strong acceleration and dependable thrust for its size. The precision carburettor and overhead-valve configuration ensure clean combustion, low vibration, and reduced fuel burn, allowing longer range on smaller tanks. Despite its modest displacement, the engine’s torque delivery at mid-rpm makes it remarkably capable when pushing heavier loads or manoeuvring in current.

Built from corrosion-resistant aluminium alloy and finished with Selva’s marine-grade coatings, the Sea Bass 6HP is engineered to endure harsh marine environments. The water-cooled, pump-forced circulation system maintains stable operating temperatures under sustained use, while the Long Shaft (L) configuration keeps the propeller immersed for better tracking and propulsion efficiency on deeper-draft hulls. The innovative oil-injection lubrication design automatically doses the intake with protective oil vapour during storage, preventing internal corrosion and reducing service requirements. Compact dimensions and a low centre of gravity make the unit stable both in operation and when mounted on a transom or auxiliary bracket.

Starting is smooth and reliable with a simple manual recoil system, while the twist-grip tiller gives precise throttle control for easy docking or slow-speed manoeuvres. Weighing around 27 kg, the Sea Bass 6HP is light enough for single-handed carrying or transom mounting. Its balanced design and vibration-dampening mounts make operation quiet and comfortable, even on long trips. Maintenance access is straightforward, oil changes, plug checks, and impeller servicing can be performed quickly without removing the cowl. Compact, quiet, and built for everyday practicality, the Sea Bass 6HP offers sailors and leisure boaters dependable power in a portable form.
