Description
Absolute propulsion simplicity defines the ultra-portable Tohatsu MFS2.5CS four-stroke outboard motor. Weighing just 18.4 kilograms, this 85.5cc water-cooled block forces steady forward thrust, pushing loaded inflatable tenders across harbor basins efficiently. Measuring your mounting bracket verifies this 15 inch short shaft portable outboard operates without dragging the gearcase excessively through shallow tidal flats.
Maneuver effortlessly through tight marina slips by leveraging the 360-degree tiller steering as a direct mechanical solution for instant reverse thrust. You rotate the engine completely backward to stop the vessel without relying on a complex internal gearbox. Tohatsu casts the lower unit using corrosion-resistant aluminum alloys. This material barrier stops rapid metal pitting when leaving the kicker motor clamped to saltwater transoms.
Key Features of Tohatsu MFS2.5CS
- 18.4 Kilogram Dry Weight: Maximizes absolute portability, allowing a single operator to lift the engine physically onto high sailboat decks.
- 15-Inch Standard Shaft: Matches low dinghy transoms perfectly, preventing lower unit drag and maximizing fuel efficiency on light hulls.
- 360-Degree Tiller Steering: Allows the operator to spin the engine completely around, providing full reverse thrust instantly without a gearbox shifter.
- Integrated 1.0L Fuel Tank: Eliminates external gas tanks and heavy fuel lines, freeing up critical floor space inside small inflatable tenders.
- 85.5cc Four-Stroke Powerhead: Produces smooth low-end torque internally, pushing heavy square-back canoes steadily against coastal tidal currents.
- Water-Cooled Engine Block: Prevents internal thermal failure completely, allowing continuous running across wide bays without overheating like air-cooled variants.
- 2.15:1 Gear Ratio: Transfers single-cylinder horsepower to the propeller securely, maintaining forward momentum on heavily loaded dinghies.
- Manual Recoil Starter: Engages the flywheel directly via a physical pull cord, guaranteeing reliable ignition without heavy 12-volt battery systems.
- Corrosion-Resistant Castings: Blocks severe galvanic decay physically, protecting the powerhead block across decades of daily saltwater exposure.
- Clean Four-Stroke Combustion: Burns unleaded fuel highly efficiently without messy two-stroke oil mixing, keeping your tender completely free of oil slicks.
Why Choose Tohatsu MFS2.5CS

Ideal Application and Vessel Fitment
This ultra-portable 15-inch outboard thrives on small inflatable tenders, square-back canoes, and rigid fiberglass dinghies requiring minimalist power. Because it features an integral fuel tank and weighs just 18.4 kilograms, operators can easily physically carry it from the main deck down to the tender. Rotating the tiller 360 degrees provides complete directional thrust, making this lightweight portable outboard motor an incredibly nimble propulsion choice for navigating crowded anchorages and tight marina fairways.
Warranty, Support and Maintenance
Authorized recreational operation receives a 5-Year Limited Warranty alongside exceptional factory support. Registered commercial applications fall under a strict 1-Year Limited Warranty with zero corrosion coverage applied to the block.
