Description
Dead marine batteries cannot stop the Tohatsu MFS20EEPS from delivering instant manual-start EFI ignition. The 333cc inline-two block forces steady forward thrust, pushing loaded inflatable tenders across choppy marina basins safely. A quick tape measure check validates this 15 inch short shaft portable outboard fits standard hulls perfectly without generating excessive hydrodynamic drag.
Navigate safely across shallow flats by utilizing the six-position manual tilt mechanism to lift the gearcase rapidly. You adjust the hull attitude directly from the tiller handle to clear submerged rocky obstacles efficiently. Engineers cast the 43 kg lower unit using corrosion-resistant marine alloys. This material barrier stops rapid metal pitting when repowering small aluminum boats in saltwater environments.
Key Features of Tohatsu MFS20EEPS
- Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating shoulder strain completely during freezing early morning launches.
- Battery-Less EFI: Atomizes fuel perfectly using internal magnetic power, guaranteeing reliable cold-weather pull starts without requiring a heavy 12-volt battery.
- 15-Inch Standard Shaft: Matches low dinghy transoms perfectly, preventing lower unit drag and maximizing fuel efficiency on light hulls.
- Six-Position Manual Tilt: Adjusts the running angle physically, allowing the operator to lift the gearcase over shallow coastal reefs safely.
- Multi-Function Tiller Handle: Concentrates shift and throttle inputs directly into your operating hand for immediate physical obstacle avoidance.
- 12-Amp Charging Alternator: Outputs constant electrical current while running, keeping small deep cycle batteries topped off for fish finders.
- 333cc Inline-Two Block: Produces massive low-end torque internally, lifting heavily loaded 12-foot rigid dinghies onto plane much faster.
- Through-Prop Exhaust: Channels toxic combustion gases directly underwater, keeping the aft operator station completely free of smoke.
- Accessible Oil Drain: Simplifies routine crankcase lubrication changes, saving significant time during seasonal maintenance prep without specialized tools.
- 2.15:1 Gear Ratio: Multiplies engine torque effectively, pushing heavily loaded hunting boats upstream against strong river currents.
Why Choose Tohatsu MFS20EEPS
You buy this motor to keep rigging dead simple on a standard 15-inch transom boat. It offers zero remote steering capability and lacks heavy power tilt components. Finding a reliable electric start portable outboard solves heavy payload limits on small hulls.
- Weigh your boat to verify it safely handles this specific 43 kg engine block mass.
- Check the tiller handle sweep path to confirm it clears your rear seating bench.
- Keep local lakes clean by running highly regulated four-stroke engine configurations.
Ideal Application and Vessel Fitment
This ultra-portable 15-inch outboard thrives on small inflatable tenders, flat-bottom jon boats, and rigid fiberglass dinghies requiring minimalist power with maximum convenience. Because it features push-button electric starting paired with battery-less EFI, operators gain absolute ignition reliability for remote area fishing. The direct tiller control provides complete directional thrust, making this lightweight 20hp electric start outboard an incredibly nimble propulsion choice for navigating crowded anchorages safely.
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. Scheduled maintenance requires replacing gearcase lubricants and changing oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. Mulmotor provides product-information support before purchase and assistance with order-related questions.
