Tohatsu MFS5DLPGSPROUL 5HP – Sail Pro LPG Propane 25-Inch

Tohatsu MFS5DLPGSPROUL 5HP Sail Pro LPG Propane

The Tohatsu MFS5DLPGSPROUL is a specialized extra-long shaft 5HP propane outboard engineered specifically for high-transom sailboats and deep-draft auxiliary applications. Built on the 123cc LPG platform and weighing 60 lbs, this unit offers the maximum propeller reach (25 inches) required for coastal sailors. This “Sail Pro” model utilizes professional marine outboard power tuned for high-thrust performance, allowing sailors to maneuver large displacement hulls through harbor chop with the mechanical confidence that only a deep-reaching propeller can provide in the North American maritime sector.

Peak operational performance is achieved between 4000 and 5000 RPM, utilizing a clean-burning propane fuel system to helps support zero-choke starting and a maintenance-free carburetor. The 2.15:1 high-thrust gearcase facilitates the mechanical translation of the 1-cylinder torque curve into steady hydrodynamic bite, even in heavy seas. This engine exemplifies Japanese engineering reliability, providing 30% fewer emissions and the security of a 5A alternator circuit to support essential sailboat electronics during long-range coastal transits.

Technical Specifications of Tohatsu MFS5D LPG Ultra-Long

• The 25-inch extra-extra-long shaft helps support maximum propeller depth for deep sailboat transoms, preventing prop ventilation in heavy swells.
• Propane (LPG) fuel induction provides 30% lower emissions and eliminates the risk of ethanol-related fuel system failure or spills.
• Sail Pro High-Thrust Propeller delivers superior pushing authority in both forward and reverse, ideal for maneuvering heavy hulls.
• A 12V 5A alternator provides steady DC charging power for essential house batteries, navigation displays, and safety lighting.
• Digital CD Ignition offers exact spark timing for a silky-smooth idle and manual starting in all maritime weather conditions.
• Manual Tilt with 6 separate positions allows for precise engine angle adjustment to minimize drag while under sail.

Auxiliary Propulsion Authority

The LPG Sail Pro technology leverages a specialized high-thrust drivetrain designed for auxiliary power. This architecture helps support the engine works efficiently at low speeds, providing the vibration dampening and mechanical strength required for pushing sailboats through unpredictable coastal tidal flows while maintaining reliable marine motor systems standards for the professional sailing community.

Clean Power Advantage

Utilizing propane as a primary fuel source means the MFS5D requires no gasoline storage on board, significantly reducing fire risks and chemical odors. The closed-loop fuel system is pressurized to helps support the engine starts on the first pull every time, providing an level of reliability for sailors who depend on their auxiliary motor for safe harbor navigation and emergency coastal maneuvering.

Tohatsu 5-Year Warranty

Every Tohatsu MFS5D LPG 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 are essential for preserving the engine’s tight mechanical tolerances. Freshwater flushing after every excursion prevents internal salt deposits and maintains cooling system health.Maintenance note: Follow the manufacturer’s service procedures and lubrication specifications for the engine and gearcase.
