Marine Specialist Insight: The Tohatsu MFS25DEFL (MPN MFS25DEFL) is a powerhouse of the 3-cylinder class. Featuring a 20-inch long shaft and Electric Start, this motor is built on Tohatsu's newly designed platform which focuses on massive low-end torque and reduced weight. With Battery-Less Electronic Fuel Injection (EFI), it provides the instant throttle response and smooth idling required for heavy tenders, pontoon boats, and commercial skiffs.
Unrivaled 3-Cylinder Performance
The Tohatsu MFS25DEFL (MPN: MFS25DEFL) brings professional-grade power to a portable 4-stroke package. The three-cylinder configuration inherently provides a smoother, more balanced operation than twin-cylinder models, resulting in significantly less vibration through the tiller and boat. This EFI model automatically adjusts to environmental factors like temperature and altitude, ensuring peak efficiency and one-pull reliability whether you are using the electric start or the manual backup.
This model features the ergonomic multi-function tiller handle, placing the gear shift, throttle control, and emergency stop switch within easy reach. The MFS25D series has been engineered to be the lightest 3-cylinder in its class, improving your boat's power-to-weight ratio for faster planing and better fuel economy. With Tohatsu’s high-output alternator, you can run fish finders, GPS units, and lights with total confidence.
