The Selva Murena EFI 40XS Extra Long Shaft is a compact yet exceptionally strong 4-stroke SOHC 16-valve outboard that converts its 996 cc displacement into the highest torque output in its class. A precision Electronic Fuel Injection (EFI) system ensures clean, efficient combustion, while a specially matched gear ratio and large-diameter propeller translate power into thrust with minimal slip. Light, quiet, and engineered for long service life, it is ideal for deep-draft craft and offshore users demanding effortless push, low vibration, and low fuel burn.

Product Description

At the heart of the Murena 40XS EFI lies Selva’s advanced 996 cc single-overhead-camshaft 16-valve powerhead. This configuration delivers broad torque and responsive acceleration throughout the 5 300 to 6 300 rpm operating band. The EFI micro-processor meters fuel precisely in real time, guaranteeing crisp throttle response, smooth cold starts, and consistent performance under load. Its generous displacement allows the engine to maintain speed without strain, reducing consumption and extending range even when driving heavier hulls

The Murena’s architecture emphasises mechanical strength and reliability. The rigid aluminium block and reinforced lower unit handle the high torque generated by the 996 cc powerhead. A 13 : 24 gear ratio, paired with a large-diameter propeller, converts torque into controlled thrust, delivering confident acceleration and steady grip in rough conditions. A sealed, pump-forced water-cooling circuit maintains optimal temperature balance, while comprehensive anti-corrosion treatments protect against salt exposure. The Extra Long Shaft (XL) layout increases propeller immersion and directional stability, ensuring precise control on deeper-draft or offshore boats.

Electric starting and EFI technology make ignition instantaneous and idling remarkably smooth. Balanced engine mounts and Selva’s precision machining reduce vibration and noise, creating a calm operating environment. The optional Power Trim and Tilt system allows effortless adjustment of running attitude, improving efficiency and handling in varying sea states. A regulated 12 V / 200 W alternator provides ample power for electronics, pumps, or navigation lights even at low rpm. Routine maintenance points are accessible without disassembly, keeping upkeep simple and downtime minimal. Refined yet robust, the Selva Murena EFI 40XS 4-Stroke Outboard Engine (Extra Long Shaft) combines advanced EFI precision with exceptional mechanical resilience, delivering quiet, efficient power that inspires confidence on every run.
