Tohatsu MFS9.9EEPS 9.9HP – EFI Electric Start Remote 15-Inch Shaft

Tohatsu MFS9.9EEPS 9.9HP EFI Electric Start Remote

The Tohatsu MFS9.9EEPS is a specialized 9.9HP outboard engineered for peak performance on small console skiffs and luxury inflatable tenders. Built on the redesigned 333cc inline 2-cylinder SOHC architecture and weighing 110 lbs, this unit offers the unique combination of short-shaft agility with the convenience of remote electric start. This 15-inch shaft model is the definitive match for boats requiring professional marine outboard power with strong low-end torque and remote handling for harbor navigation and high-speed coastal transit.

Peak operational performance occurs between 5400 and 6100 RPM, delivering instant throttle response via the advanced EFI system. The 2.15:1 gear ratio facilitates the mechanical translation of 333cc power into steady hydrodynamic authority and reliable hull control. This engine exemplifies Japanese engineering excellence, ensuring the corrosion-resistant block maintains high thermal efficiency while providing the refined, vibration-free experience that serious recreational boaters expect from a next-generation Tohatsu 9.9HP unit across the United States.

Short Shaft Console Tech

The FourStroke 9.9HP EFI technology leverages its 333cc architecture to maximize intake efficiency across the power band. This sophisticated design helps support strong acceleration, providing the mechanical integrity needed for tournament-level fishing while maintaining reliable marine motor systems standards for small craft captains navigating coastal tidal mudflats and rivers.

Precision EFI Logic

The Electronic Fuel Injection system monitors atmospheric variables to provide the appropriate fuel induction ratio for peak performance. This technology is designed to support instant response and prevents engine bogging, completely eliminating carburetor-related maintenance while providing rapid acceleration and clean combustion for professional long-range trips in performance-driven coastal saltwater maritime environments.

Tohatsu 5-Year Warranty

Every Tohatsu MFS9.9E is backed by a comprehensive 5-Year Limited Warranty for American boat owners. This high-pressure protection covers structural and mechanical defects, ensuring access to genuine replacement parts and certified technicians through a vast nationwide dealer network, reflecting a deep commitment to long-term maritime reliability.

Maintenance & Longevity

Routine oil changes for the 1.0-liter wet sump system are essential for preserving the engine’s tight mechanical tolerances in saltwater. Freshwater flushing after every excursion prevents internal salt deposits and maintains the cooling system health.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
