Tohatsu MFS40AJETETL 40HP 20in Jet Standard Configuration Outboard Motor

Description

Attain push-button power tilt with the Tohatsu MFS30DETS Marine Outboard Engine for harbor service. Built with an integrated power tilt unit and a 15-inch shaft, this 500 cc D-Series three-cylinder powerhead generates 30 continuous horsepower at 5500 to 6500 RPM. Electronic fuel injection combines with remote controls across commercial work transoms.

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 ring wear during continuous commercial operation. The 15-inch short shaft midsection houses an integrated electro-hydraulic power tilt actuator and stainless steel driveshaft. Base dry engine weight reaches 132 lbs without propeller. The internal wet sump stores 1.8 quarts of motor oil, monitored through an integrated oil inspection window.

Key Features of Tohatsu MFS30DETS

Commercial fleet owners buy Tohatsu MFS30DETS outboard engine units for remote-steered tender propulsion on commercial motherships and skiffs. Integrated electro-hydraulic power tilt allows operators to raise the lower unit from helm consoles.

• Electro-hydraulic power tilt mechanisms lift the lower unit out of the water with push-button helm switches.
• 15-inch driveshaft configurations align with standard commercial dinghy and skiff transoms without brackets.
• Electronic fuel injection produces immediate electric key starts without requiring manual choking.
• Remote control binnacle boxes integrate forward-neutral-reverse shifting with smooth throttle cable action.
• 500 cc displacement D-Series three cylinder blocks generate massive torque with lowest-in-class dry weight.
• Tohatsu MFS30DETS commercial vessel performance engineering eliminates vapor lock through pressurized fuel circuits.
• High thrust propellers swing broad blade surfaces for increased stopping control in reverse gear.

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 Installation Interface Geometry

Through-hub exhaust pathways discharge spent combustion gases underwater behind the propeller blade pattern to lower deck noise. Heavy duty transom bracket pads bolt across standard 15-inch boat transoms with four stainless steel fasteners. Heavy elastomer isolation dampers decouple engine vibration from aluminum hulls. Integrated power tilt rams provide full transom travel clearance.

Harbor Shift Service Protocols

Remote helm binnacles 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 on this marine powerhead. The export carton contains the complete MFS30DETS outboard motor, remote control binnacle, wiring harness, an external 6.6-gallon fuel tank with hose, maintenance tool kit, and aluminum three blade propeller.
