Tohatsu MFS20EEFTL 20HP 20in Standard Configuration Outboard Motor

Description

Featuring a 333 cc displacement block, the Tohatsu MFS20EEFTL Marine Outboard Engine powers commercial craft. Built with a 20-inch long shaft column, this twin-cylinder four stroke powerhead generates 20 continuous horsepower at 5400 to 6100 RPM. Battery-less electronic fuel injection pairs with electric start to provide dependable propulsion across tall tenders.

Engineers cast the compact twin-cylinder engine block from marine grade aluminum alloy treated with anti-corrosion finishes. Centrifugal cast iron cylinder sleeves resist piston ring wear during continuous commercial operation. The extended 20-inch midsection houses an electric starter motor and stainless steel driveshaft supported by heavy roller bearings. Base dry engine weight reaches 101 lbs without propeller. The internal wet sump stores 1.1 quarts of motor oil, monitored through an integrated oil inspection window.

Key Features of Tohatsu MFS20EEFTL

Commercial fleet owners buy Tohatsu MFS20EEFTL outboard engine units for high-thrust auxiliary propulsion on commercial work sailboats and tenders. The extended 20-inch shaft prevents propeller ventilation when operating in choppy harbor conditions.

• 20-inch driveshaft configurations align with deep commercial sailboat and utility workboat transoms.
• Battery-less electronic fuel injection produces immediate engine starts without requiring a heavy battery.
• Electric key start systems pair with backup manual recoil cords for fail-safe starting assurance.
• 333 cc displacement twin cylinder blocks provide high torque to push heavy displacement hulls.
• Ergonomic tiller handles integrate gear shifting, throttle grip friction, and stop buttons in reach.
• Tohatsu MFS20EEFTL commercial vessel performance engineering eliminates vapor lock through pressurized fuel circuits.
• Five-position manual trim pin adjustments allow operators to navigate shallow harbor river shoals.

Thermodynamic Combustion Profile Thresholds

Thermostat regulators maintain coolant temperatures between 135°F and 155°F inside cooling jackets to eliminate salt buildup. Twin cylinders operate at 9.0 to 1 compression to generate 20 continuous horsepower at 5750 RPM under commercial auxiliary duty ratings. Overhead cams produce strong low-end torque when pushing heavy equipment payloads against harbor currents. Specific fuel consumption averages 1.45 GPH under full load operation. Internal raw water channels route engine heat into through-propeller exhaust paths to protect internal components during long continuous shifts.

Transom Clamp Clearance Parameters

Through-hub exhaust pathways discharge spent combustion gases underwater behind the propeller blade pattern to lower deck noise. Dual manual clamp screws anchor the transom mounting bracket across standard 20-inch boat transoms. Heavy elastomer isolation dampers decouple engine vibration from aluminum hulls. Manual tilt pins lock into five positions to navigate shallow water.

Harbor Shift Service Protocols

Integrated tiller controls actuate forward, neutral, and reverse gear engagement without binding. Operators monitor the cooling water telltale stream to verify raw water impeller suction before departure. This outboard motor is not engineered for lightweight racing hulls, surface mud drives, or vessels operating without clean raw water intake flow.

• Inspect raw water intake grates for weed blockages before each shift begins.
• Drain crankcase engine oil and replace lower gearcase lubricant every 100 hours.
• Replace engine spark plugs and inspect external zinc anodes every 12 months.

Commercial Warranty Crate Specifications

Tohatsu provides 3-year commercial or 5-year recreational limited factory warranty coverage. The export carton contains the complete MFS20EEFTL outboard motor, an external 3.1-gallon fuel tank with hose, battery connection cables, operator service manual binder, maintenance tool kit, and standard aluminum three blade propeller.
