Product Description

Compact and responsive, the Oyster 6 Big Foot Sail produces its 6 horsepower (4.4 kW) output through a robust 135 cc SOHC four-stroke engine. Operating smoothly between 5 500 and 6 000 rpm, it provides dependable torque for manoeuvring in marinas or powering against wind and current. The single-overhead-camshaft layout and finely balanced crankshaft minimise internal friction, improving efficiency and extending engine life. With careful combustion control and low specific fuel consumption, the Oyster delivers impressive range on minimal fuel.

The Big Foot gearbox is the heart of this model’s capability. Its enlarged, heavy-duty casing supports a large-diameter propeller, translating low-speed torque into effective thrust even at modest rpm—an advantage when pushing a sailing yacht’s displacement hull. The Extra Long Shaft (XL) configuration keeps the propeller deeply immersed, maintaining bite and directional control even when the boat heels or pitches. Built from corrosion-resistant aluminium alloy and coated with Selva’s multi-layer marine protection, the engine withstands continuous exposure to saltwater. Pump-forced water-cooling stabilises temperature under extended running, while the compact cowl design offers easy access for maintenance.

Starting is quick and simple through the manual recoil system, and vibration is absorbed by Selva’s tuned mounting points. The twist-grip tiller gives precise throttle control, allowing effortless speed adjustments in tight spaces. Manual trim settings let the operator fine-tune the motor’s running angle for maximum efficiency under sail or auxiliary power. Light in weight yet steady in operation, the Oyster 6 Big Foot Sail XL offers smooth, predictable handling, making it an ideal companion for both novice and experienced sailors. Compact, quiet, and built for endurance, the Selva Oyster 6 HP Big Foot Sail 4-Stroke Outboard Engine (Extra Long Shaft) provides the perfect balance between portability and propulsion for small to medium sailboats.
