The Tohatsu MFS100AJETETUL is engineered for boaters who navigate shallow rivers, rocky shoals, and rugged backwater stretches where conventional propeller drives simply can’t reach. Built on the proven MFS90/115/140 platform, this jet drive outboard inherits the same compact, lightweight design that has made Tohatsu’s mid-range four-strokes a favorite among serious boaters. At just 414.5 pounds, the MFS100AJETETUL is the lightest 100 HP jet drive in its class — a meaningful advantage when transom weight directly affects boat performance, handling, and shallow-water capability.

Power comes from a 4-cylinder, 1995cc EFI four-stroke producing a Jet Power rating of 100 HP. The unique SOHC-4V cylinder head design — exclusive to this class — combined with electronic fuel injection delivers smooth acceleration, dependable cold-weather starts, and the fuel efficiency Tohatsu is known for. The 4-2-1 Performance Tuned Exhaust system, inherited from the MFS140 lineage, optimizes torque throughout the RPM range, giving you strong hole shots and confident planing even in shallow-draft conditions.
Standard equipment on this configuration includes electric start for effortless ignition, power trim and tilt for quick adjustment on the water, and a 25-inch ultra-long shaft suited to larger jet boats and aluminum hulls running raised transom setups. A robust 12V, 492-watt, 41-amp alternator keeps electronics, livewells, and batteries powered, while high-solid paint and corrosion-resistant construction stand up to saltwater, brackish bays, and silty river conditions.

Practical touches make the Tohatsu 100 HP outboard exceptionally user-friendly. Adjustable idle and trolling speed lets you fine-tune RPM in five steps between 650 and 850 RPM — ideal for slow-speed maneuvering in tight quarters or controlled drifts while fishing. TOCS (Tohatsu Onboard Communication System) provides plug-and-play connection between the outboard and onboard electronics, so adding a multifunctional tachometer, trim meter, or other gauges is straightforward. Compatibility with both Multi-Function Tiller Handle and remote control systems gives you full flexibility in how your boat is rigged.

With EPA and CARB 3-Star emissions compliance, the MFS100AJETETUL meets the strictest clean-running standards while delivering the durability and low-maintenance ownership Tohatsu has built since 1956. Whether you’re running skinny water for redfish, exploring rocky inland rivers, or repowering a jet sled, the Tohatsu MFS100AJETETUL offers a rare combination of light weight, real power, and proven Japanese engineering that’s hard to match — backed by Northeast Marine for sales, rigging, and service support.
