Tohatsu MFS140AWETUL 140HP – 25″ Shaft Standard Rotation Tiller or Remote

Tohatsu MFS140AWETUL 140HP FourStroke EFI (Beluga White)

The Tohatsu MFS140AWETUL pairs a 1995cc inline 4-cylinder SOHC engine with standard rotation, finished in Beluga White at 401 lbs. Built for high-transom offshore vessels in Mulmarine’s marine outboard power lineup, the 25-inch shaft gives maximum propeller reach and a refined aesthetic in unpredictable saltwater environments.

Peak output holds between 5150-5850 RPM, translating the 2.0L displacement into a smooth torque curve via the performance-tuned 4-2-1 exhaust. The 2.08:1 gear ratio translates power into hole-shot capability and steady hull planing. This engine reflects Japanese engineering standards, with a corrosion-resistant Beluga White housing for thermal efficiency and electrical capacity.

Technical Specifications of Tohatsu MFS140AWETUL

• The 1995cc inline 4-cylinder SOHC 16-valve powerhead uses a 4-2-1 isometric exhaust manifold for low-to-mid range torque.
• The Beluga White finish ensures long-term UV resistance and a high-end look on modern offshore fiberglass hulls.
• Electronic Fuel Injection (EFI) ensures reliable zero-choke starting and strong thermal efficiency.
• The 25-inch extra-long shaft ensures maximum propeller depth to prevent cavitation in rolling offshore conditions.
• A 41-Amp alternator (492W) delivers charging power to support high-draw navigation systems and safety electronics.
• Trochoid pump lubrication ensures consistent oil pressure during sustained high-displacement operation.

Isometric Exhaust Technology

The 2.0L architecture and innovative exhaust design maximize low-end thrust across the power band, giving the vibration dampening and mechanical strength needed for pushing heavy fiberglass hulls through coastal tidal flows.

Precision EFI Induction

EFI monitors atmospheric variables for the right fuel induction ratio, guaranteeing instant starting and eliminating carburetor-related maintenance.

Tohatsu 5-Year Warranty

Every Tohatsu MFS140A carries a 5-year limited warranty, with genuine parts and certified technicians through a nationwide dealer network.

High-Transom Elite Application

This 140HP Beluga White unit suits high-transom offshore walkarounds and luxury center consoles needing aggressive power, well matched for coastal tournament fishing.

Maintenance & Longevity

Routine oil changes for the 4.4-quart wet sump system preserve the engine’s tight mechanical tolerances. Pro Tip from the Shop: periodically grease the steering tube and check the prop shaft seals for fishing line intrusion.
