Tohatsu 140hp MFS140AETCUL Outboard Motor

Overview Tohatsu 140hp MFS140AETCUL Outboard Motor

The Tohatsu 140hp MFS140AETCUL Outboard Motor is a high-output EFI four-stroke engine designed specifically for twin-engine applications that require counter-rotation and maximum control. Featuring a 25” extra-long shaft and opposite-rotation lower unit, this model improves handling balance, reduces steering torque, and enhances overall maneuverability on offshore and commercial vessels.

Built with industry-first 4-2-1 Performance Tuned Exhaust technology and Simpliq™ SOHC-4V engine architecture, the MFS140AETCUL delivers exceptional low-end torque, smooth acceleration, and impressive fuel efficiency—often matching the real-world performance of heavier 150hp outboards without the added weight.
