Description
Treacherous rock-strewn rivers yield immediately to the Tohatsu MFS65AJETETUL as it forces high-pressure water directly through the pump volute. The 866cc EFI block generates massive internal power to offset jet pump parasitic loss, delivering 45-50 horsepower of pure thrust. Confirming your hull geometry ensures this 65hp jet drive outboard mounts securely to specifically cut jet transoms without risking intake starvation.
Eradicate catastrophic lower unit gearcase destruction entirely by utilizing the direct-drive jet pump architecture to navigate shallow shoals. You glide over submerged gravel bars effortlessly while the factory power trim instantly adjusts your running draft from the helm. Engineers build the 107 kg assembly with impact-deflecting marine aluminum, establishing a rigid physical barrier that stops rapid metal pitting during shallow water river navigation.
Key Features of Tohatsu MFS65AJETETUL
- Direct Drive Jet Pump: Eliminates the vulnerable lower unit gearcase entirely, allowing safe navigation over shallow rocky riverbeds without catastrophic drivetrain damage.
- 866cc Powerhead Block: Generates 65 horsepower internally to offset jet pump parasitic loss, delivering a true 45-50 horsepower of thrust at the nozzle.
- Hydraulic Power Trim: Adjusts the running angle actively via a console switch, optimizing hull attitude instantly to maintain a flat, shallow draft.
- 25-Inch Jet Configuration: Designed specifically for 25-inch tall jet transoms, placing the intake grate perfectly flush with the flat hull bottom.
- Versatile Steering Compatibility: Accepts standard mechanical remote cables or advanced multi-function tiller handles depending on your specific shallow-water boat layout.
- 21-Amp Charging Alternator: Outputs massive electrical current underway, powering essential navigation lights and multiple fish finders reliably against strong river currents.
- Turn-Key Electric Start: Engages the flywheel instantly via 12-volt battery power, eliminating physical pull strain completely during freezing early morning launches.
- 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.
- Clean Four-Stroke Combustion: Burns fuel highly efficiently without oil mixing, easily meeting strict local waterway emissions regulations and EPA standards.
Why Choose Tohatsu MFS65AJETETUL
You select this specialized jet outboard strictly to run extreme shallow water rivers. It demands a flat-bottom hull with a specifically cut 25-inch transom to align the jet intake properly. Sourcing a power tilt jet outboard prevents costly downtime.
- Confirm your flat-bottom aluminum hull features a specifically modified 25-inch jet-cut transom.
- Install corresponding mechanical control cables or a compatible tiller handle setup.
- 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 fiberglass jon boats, and commercial 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.
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.
