Tohatsu MFS140AWETCUL 140HP – 25″ Shaft Counter Rotation Tiller or Remote

Tohatsu MFS140AWETCUL 140HP Counter Rotation (Beluga White)

The Tohatsu MFS140AWETCUL pairs a 2.0L inline 4-cylinder SOHC engine with counter-rotation gearing, finished in Beluga White at 401 lbs. The 4-2-1 performance tuned exhaust gives strong torque, and the 25-inch extra-long shaft suits twin-engine offshore configurations in Mulmarine’s marine propulsion units lineup that need to eliminate propeller torque.

Peak output holds between 5150-5850 RPM, delivering immediate throttle response at the helm. The 2.08:1 counter-rotation gearcase translates power into steady hull planing and directional stability. This engine reflects Japanese engineering standards, with a corrosion-resistant Beluga White finish for thermal efficiency and vibration dampening.

Technical Specifications of Tohatsu MFS140AWETCUL

• The 1995cc L4 16-valve SOHC powerhead uses a 4-2-1 performance exhaust manifold to maximize low-end torque and acceleration.
• Counter-rotation gearcase (left-hand) eliminates steering pull and improves handling in dual-engine offshore setups.
• Beluga White finish resists UV fading and salt corrosion in harsh saltwater climates.
• 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 navigation systems and safety electronics.
• Electronic Fuel Injection (EFI) ensures reliable zero-choke starting and strong thermal efficiency.

4-2-1 Exhaust Performance

The isometric exhaust manifold design maximizes air flow and minimizes interference between cylinders, giving the mechanical integrity needed for tournament-level fishing and high-speed coastal transit.

Precision EFI Induction

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

Hydrodynamic Shaft Authority

The counter-rotating propellers and 25-inch hydrodynamic shaft keep consistent propeller grip in deep swells, giving the captain boat control during complex harbor maneuvers.

Tohatsu 5-Year Warranty

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

Offshore Twin-Engine Match

This engine suits high-transom offshore walkarounds and luxury center consoles in dual-engine configurations, well matched for tournament fishing.

Maintenance & Longevity

Maintaining the 4.2-liter oil capacity in the L4 wet sump system preserves engine tolerances under heavy loads. Pro Tip from the Shop: periodically wax the Beluga White cowling and verify the counter-rotation propeller is correctly seated before every multi-engine transit.
