Product Description

The Selva Oyster 6HP Short Shaft delivers impressive thrust from a refined 135 cc 4-stroke OHC engine, producing smooth power across the 5,000 – 5,500 RPM range. The advanced Overhead Camshaft design reduces friction and improves valve timing accuracy, resulting in stronger torque, quicker throttle response and cleaner combustion. This innovation makes the Oyster exceptionally quiet, fuel-efficient and compliant with the most stringent emission standards.

Compact, balanced and purpose-built, the Oyster 6HP is made for portability and longevity. Its lightweight frame and corrosion-resistant aluminium housing ensure dependable operation in both salt and freshwater. The Short Shaft configuration gives precise handling on smaller hulls, with smooth steering response and excellent low-speed control. A durable gearbox and efficient cooling system guarantee long-term reliability with minimal maintenance.

Engineered for simplicity, the Oyster 6HP offers easy manual starting, smooth idling and precise throttle adjustment via its ergonomic tiller handle. Maintenance points are easily accessible, and the clean 4-stroke design eliminates oil mixing, making it as simple to operate as a 2-stroke, yet quieter and more efficient. Its lightweight structure also allows easy lifting, transport and installation. The Selva Oyster 6HP 4-Stroke Outboard Engine (Short Shaft) combines cutting-edge OHC technology with Selva’s trusted marine craftsmanship, offering a clean, quiet and efficient power solution that’s built to last.
