Tohatsu MFS115AWETL 115HP EFI 4-Stroke Outboard Motor

The Tohatsu MFS115AWETL 115HP Outboard Motor is engineered to deliver reliable power, advanced fuel efficiency, and smooth performance for modern boaters. Manufactured by Tohatsu Corporation, this high-performance four-stroke outboard combines innovative engineering with durable marine components to provide outstanding reliability in both recreational and light commercial marine applications.

The MFS115 series includes several advanced features that improve overall boating performance and ease of operation. One of the most useful innovations is the Variable Idle System, which allows the operator to adjust the engine’s idle speed between 650 and 850 RPM. This feature improves control during trolling, docking, and slow-speed maneuvering.

The engine also features a low 2.08:1 gear ratio, which increases low-end torque and improves acceleration. This design allows boats to reach plane faster while delivering smooth and consistent power delivery.

Maintenance is simplified with the built-in freshwater flushing system, allowing quick and convenient flushing after saltwater use. This helps maintain engine performance and extend the life of internal components.

For onboard electrical needs, the MFS115 is equipped with a high-output 41-amp alternator, providing reliable power for marine electronics such as GPS units, fish finders, lighting systems, and charging batteries.

The engine’s SOHC-4 valve design delivers excellent fuel economy while maintaining strong performance and quiet operation. In fact, the MFS115 is designed to provide one of the quietest idle operations in its class, ensuring a more comfortable boating experience.

This model features a 20-inch long shaft, making it suitable for a wide variety of boats, including fishing vessels and recreational powerboats. The engine is available with tiller steering or remote mechanical controls, allowing flexibility for different boat configurations.

In addition, the MFS115 series meets Ultra-Low Emission standards, with CARB 3-Star and EPA approval, ensuring environmentally responsible performance.

Backed by a 5-Year Manufacturer Warranty, the Tohatsu 115HP EFI Outboard Motor offers long-term durability, efficiency, and peace of mind for boat owners.
