Description
Premium inflatable tenders gain immediate ignition reliability with the Tohatsu MFS9.8CEFS clamped securely to the transom. This 209cc twin-cylinder block translates 12-volt starting power into smooth low-end torque, navigating choppy harbor basins effortlessly. A quick tape measure check validates this 15 inch short shaft portable outboard fits standard hulls perfectly without causing dangerous water pump starvation.
Maintain constant battery voltage while slow trolling by utilizing the integrated 6-amp alternator as a reliable electrical generator. You keep essential navigation lights glowing brightly across dark marina basins without draining deep cycle batteries. Engineers build the 38 kg assembly with low-copper marine aluminum. This physical barrier stops galvanic decay when repowering small fiberglass skiffs in harsh saltwater environments.
Key Features of Tohatsu MFS9.8CEFS
- Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating shoulder strain completely during freezing early morning launches.

- Weigh your boat to verify it safely handles this specific 38 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 a manual recoil backup, operators gain absolute ignition reliability for remote area fishing. The direct tiller control provides complete directional thrust, making this lightweight 9.8hp 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.
