2027 Yamaha Four Stroke Midrange 1.8L F90XB
Description
Meet the 2027 Yamaha Fourstroke F90XB in classic Yamaha Gray—a midrange outboard that’s built to make everyday boating feel effortless, whether you’re chasing sunrise runs, towing the kids, or piling on gear for a full day on the water. This is an engine-only listing (not a complete boat), ready to be paired with the right hull and rigging.
With 90 hp (67.2 kW) at 5500 RPM from a 1.8L (1832 cc) in-line 4-cylinder, this Four Stroke delivers the kind of confident, usable power that shines on the hulls it’s commonly matched with—think mid-size center consoles, bay boats, aluminum fishing rigs, and family runabouts that want strong hole-shot and clean midrange pull without jumping into heavyweight power. The SOHC, 16-valve (4 per cylinder) design and 10.0:1 compression help it breathe efficiently, while fuel injection keeps throttle response crisp and starts reliable.
For day-to-day boating, the sweet spot is the cruise—and this engine is designed for it. Running regular gas, and with a midrange-friendly displacement, the F90XB is a great choice for boaters who want solid performance while keeping fuel stops less frequent on long shoreline hops or all-day trolling and scouting missions.
It’s also ready for real marine duty: salt water capable, water (open loop) cooling, and a built-in visual/audible engine alert system with emergency RPM reduction to help protect your investment when conditions (or distractions) happen.
Rigging-wise, this model features a 25-inch shaft and remote steering control, paired with a power trim system for easy attitude adjustments as loads and water conditions change. Power for onboard needs is supported by a 35-amp alternator, and the 2.15:1 gear ratio is tuned for efficient prop-driven thrust. Dry weight is a manageable 362 lbs, keeping transom weight sensible for the class.
If you’re looking for a modern, dependable midrange outboard in Yamaha Gray that’s sized right for versatile coastal and inland hulls, the Yamaha F90XB is ready to power the next season. Warranty coverage may apply—contact us for current details and rigging compatibility.
