Tohatsu MFS25DWETS 25HP 15in Standard Configuration Outboard Motor

Description

During continuous harbor tender duties, the Tohatsu MFS25DWETS White Outboard Engine maintains dependable authority. Built with an integrated power tilt unit, 15-inch shaft, and Beluga White finish, this 500 cc D-Series three-cylinder powerhead generates 25 continuous horsepower at 5000 to 6000 RPM. Electronic fuel injection pairs with remote controls on tenders.

Engineers cast the lightweight D-Series three-cylinder block from marine grade aluminum alloy coated with multi-layer Beluga White polyurethane paint. 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 oil inspection window.

Key Features of Tohatsu MFS25DWETS

Commercial fleet owners buy Tohatsu MFS25DWETS 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.

• Beluga White multi-layer paint coatings protect aluminum castings from UV solar breakdown and salt corrosion.
• 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 MFS25DWETS commercial vessel performance engineering eliminates vapor lock through pressurized fuel circuits.

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 25 continuous horsepower at 5500 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 1.75 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 MFS25DWETS outboard motor, remote control binnacle, wiring harness, an external 6.6-gallon fuel tank with hose, maintenance tool kit, and aluminum three blade propeller.
