Description
Tohatsu MFS9.8CWEFUL – Professional Overview
The Tohatsu MFS9.8CWEFUL is a 9.8hp four-stroke portable outboard designed for boat owners who need a compact propulsion solution without moving into a larger and heavier engine class.
The MFS9.8 family uses a two-cylinder, 209cc engine with a SOHC four-valve configuration. Tohatsu’s published specifications identify a maximum output of 7.2 kW (9.8 HP) and an operating range of approximately 5,000–6,000 rpm.
This particular product configuration is supplied with a 20-inch long shaft, tiller operation, electric and manual starting, manual trim and tilt, and standard rotation. These specifications make correct boat and transom compatibility particularly important when selecting the engine.
Compatibility and Intended Applications
The MFS9.8CWEFUL is intended for compatible boats requiring 9.8hp outboard propulsion and a 20-inch shaft.
The tiller-control configuration makes it particularly relevant to smaller vessels where direct control from the engine is preferred. Potential applications include fishing boats, small utility boats, tenders, inflatables, and other compatible craft designed around portable outboard propulsion.
Tohatsu identifies the MFS9.8 as a tiller or remote-control-capable model family, while the supplied product configuration specifically identifies this model as a tiller-controlled engine.
Before ordering, the boat’s transom height should be checked against the 20-inch shaft specification.
Two-Cylinder Four-Stroke Performance
The Tohatsu 9.8hp outboard uses a two-cylinder four-stroke engine with a 209cc displacement. Tohatsu’s published specifications list a 55 × 44 mm bore and stroke and a maximum operating range of 5,000–6,000 rpm.
The four-stroke configuration is designed for marine propulsion rather than high-speed automotive use, with water cooling and a dedicated marine lower unit.
At 9.8hp, the engine occupies a useful position for buyers who need more propulsion than a very small portable outboard provides while still wanting a relatively compact engine package.
Electric and Manual Starting
One of the practical features of the MFS9.8CWEFUL configuration is its combination of electric and manual starting.
Electric starting provides convenient engine activation when the appropriate electrical system is installed, while the manual-start capability provides an additional starting method.
Tohatsu’s technical information confirms that the MFS9.8 family is available with electric and manual starting configurations.
The exact equipment supplied with an individual configuration should always be confirmed against the product specification before purchase.
Tiller Control and Manual Trim
The supplied configuration uses a tiller control system, allowing the operator to control the outboard directly from the engine.
It also uses manual trim and tilt rather than power trim. This keeps the configuration relatively straightforward and is appropriate for boats where manual engine-position adjustment is suitable.
Tohatsu’s MFS9.8 information identifies tiller-handle operation within the model family, along with manual-start and electric-start variants.
20-Inch Long Shaft Configuration
The 20-inch long shaft is one of the most important fitment details for this outboard.
Shaft length determines how the engine sits relative to the boat’s transom and underwater hull. Selecting the correct shaft length helps position the propeller appropriately for the vessel’s intended installation.
The supplied product information identifies this particular MFS9.8CWEFUL as a 20-inch long-shaft configuration. Buyers replacing an existing engine should compare the current shaft length and transom requirements rather than selecting based solely on horsepower.
Practical Marine Design
The MFS9.8 is built around a compact marine propulsion platform. Tohatsu’s published specifications identify water cooling, a 2.08:1 gear ratio, and a 12V charging output for applicable MFS9.8 configurations.
The engine’s compact two-cylinder architecture also keeps it within the portable-outboard segment while providing 9.8hp of output.
For customers comparing different small outboards, the combination of horsepower, starting system, shaft length, control type, and engine weight should be considered together rather than focusing on horsepower alone.
Who This Outboard Is Best For
The Tohatsu MFS9.8CWEFUL is best suited to boat owners who need a compact 9.8hp outboard with tiller control and a 20-inch shaft.
It can be particularly relevant for:
- Small fishing boats
- Tenders and utility boats
- Compatible inflatable boats
- Recreational boats requiring portable propulsion
- Owners replacing a compatible 9.8hp outboard
- Buyers wanting both electric and manual starting
The engine should be selected after confirming the boat’s transom height, maximum rated horsepower, control requirements, and shaft-length requirements.

Ordering, Fitment, and Support
Before purchasing the Tohatsu MFS9.8CWEFUL, buyers should confirm that their boat is rated for the engine’s 9.8hp output and that a 20-inch shaft is appropriate for the transom.
The control configuration should also be checked carefully. This product is specified with tiller control, so it is different from MFS9.8 configurations intended for remote helm controls.
For customers maintaining or servicing the engine, Tohatsu provides technical information, owner manuals, and parts resources for its outboard range.
Customers comparing this engine with other Tohatsu outboard motors can also review different horsepower, shaft-length, starting, and control configurations within the outboard collection.
Frequently Asked Questions
How much horsepower does the Tohatsu MFS9.8CWEFUL produce?
The Tohatsu MFS9.8CWEFUL produces 9.8hp, equivalent to approximately 7.2 kW. It uses a two-cylinder, 209cc four-stroke engine designed for compatible small-boat and portable marine applications.
Is the Tohatsu MFS9.8CWEFUL electric start?
Yes. The supplied configuration specifies electric + manual starting. This provides electric starting convenience while retaining a manual starting capability. Exact battery and electrical installation requirements should be confirmed for the specific configuration.
What shaft length does this Tohatsu 9.8hp outboard have?
This configuration has a 20-inch long shaft. Buyers should verify that their boat’s transom is designed for a 20-inch outboard before ordering.
Does the MFS9.8CWEFUL use tiller or remote controls?
