Tohatsu MFS100AJETETUL 100HP Outboard – 25in, Jet Drive

Description

Shallow river running takes a massive leap forward with the 1.9-liter Tohatsu MFS100AJETETUL forcing high-pressure water directly through the pump volute. The 16-valve inline-four block generates 100 horsepower internally to offset jet pump parasitic loss, delivering massive jet thrust for heavy aluminum sleds. Verifying your hull geometry confirms this 25 inch jet drive tohatsu outboard mounts perfectly to tall 25-inch jet transoms without risking intake starvation.

Eradicate catastrophic lower unit destruction completely by utilizing the direct-drive jet pump architecture to navigate treacherous rock-strewn rivers. You glide over shallow gravel bars effortlessly while the factory power trim instantly adjusts your running draft. Tohatsu engineers the 189 kg assembly with impact-deflecting marine aluminum. This structural barrier stops rapid metal pitting when repowering aluminum river boats in harsh environments.

Key Features of Tohatsu MFS100AJETETUL

• Direct Drive Jet Pump: Eliminates the vulnerable lower unit gearcase entirely, allowing safe navigation over shallow rocky riverbeds without catastrophic drivetrain damage.
• 1.9-Liter Powerhead Block: Generates 100 horsepower internally to offset jet pump parasitic loss, delivering 70-75 horsepower of pure thrust at the nozzle.
• 25-Inch Ultra-Long Shaft: Mounts specifically to tall 25-inch jet transoms, placing the jet water intake perfectly flush with the flat hull bottom.
• Electronic Fuel Injection: Atomizes fuel perfectly across the 5000-6000 RPM range, eliminating carburetor jet clogging and guaranteeing crisp throttle response.
• Hydraulic Power Trim: Adjusts the running angle dynamically via a console switch, optimizing hull attitude instantly to maintain a flat, shallow draft.
• 35-Amp Charging Alternator: Outputs massive electrical current underway, powering essential navigation lights and multiple fish finders reliably against strong river currents.
• Impact-Deflecting Alloy Housing: Forms a rigid structural barrier around the jet pump volute, defying severe abrasion from gravel and sand ingestion.
• Through-Pump Exhaust: Channels toxic combustion gases directly into the high-velocity water stream, keeping the operator station completely free of smoke.
• Accessible Oil Drain: Simplifies routine crankcase lubrication changes, saving significant time during seasonal maintenance prep without requiring specialized dealership tools.
• Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.

Why Choose Tohatsu MFS100AJETETUL

You select this specialized jet outboard strictly to run extreme shallow water rivers. It demands a flat-bottom hull with a 25-inch tall jet transom to align the jet intake properly. Substituting a standard propeller model will cause immediate lower unit destruction. Securing a reliable remote steer jet outboard prevents costly downtime.

• Confirm your flat-bottom aluminum hull features a strict 25-inch jet-cut transom.
• Install corresponding mechanical control cables sized exactly for your specific boat length.
• Meet strict lake emission standards via certified low-emission combustion processes.

Ideal Application and Vessel Fitment

This specialized jet outboard is built exclusively for flat-bottom aluminum river sleds, shallow-draft jon boats, and large skinny-water workboats. Because the direct-drive jet pump sits flush with the hull bottom, it completely eliminates the draft penalties of a standard propeller, allowing operators to run on plane across mere inches of water. It thrives in treacherous, rock-strewn rivers where traditional gearcases would instantly shatter, delivering unmatched backcountry access for extreme anglers requiring heavy payload capacity.

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 greasing jet pump bearings and changing powerhead 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.
