Tohatsu MFS40AWETL 40HP 20in EFI White Outboard Motor

Description

During commercial harbor patrol shifts, the Tohatsu MFS30DL Marine Outboard Engine maintains dependable thrust. Built with a 20-inch long shaft column and remote linkage, this 500 cc D-Series three-cylinder powerhead generates 30 continuous horsepower at 5500 to 6500 RPM. Battery-less fuel injection pairs with manual start across commercial workboat hulls.

Engineers cast the lightweight D-Series three-cylinder block from marine grade aluminum alloy treated with anti-corrosion finishes. Centrifugal cast iron cylinder sleeves resist piston wear under extended low-speed trolling. The 20-inch long shaft midsection incorporates heavy duty manual clamp brackets to anchor across workboat transoms. Base dry engine weight reaches just 128 lbs without propeller. The wet sump stores 1.8 quarts of motor oil, checked via an integrated sight glass.

Key Features of Tohatsu MFS30DL

Shipyards buy Tohatsu MFS30DL outboard engine units to power commercial work dinghies and auxiliary skiffs. Battery-less electronic fuel injection eliminates heavy starting batteries while producing rapid recoil starts in freezing weather.

• Battery-less electronic fuel injection meters fuel with precision without requiring an external battery pack.
• 20-inch driveshaft configurations align with deep commercial sailboat and utility workboat transoms.
• Manual recoil starting mechanisms utilize low compression cams for smooth rope pull effort.
• 500 cc displacement D-Series three cylinder blocks generate massive torque with lowest-in-class dry weight.
• Remote control connections link straight to standard steering cables and throttle binnacle boxes.
• Tohatsu MFS30DL 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. Three cylinders operate at 9.5 to 1 compression to generate 30 continuous horsepower at 6000 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 2.15 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

Remote control binnacle levers 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 MFS30DL outboard motor, an external 6.6-gallon fuel tank with hose, spare pull rope, operator service manual binder, maintenance tool kit, and standard aluminum three blade propeller.
