2027 Yamaha Four Stroke Midrange 1.8L F90XB2
Description
Meet the midrange muscle that makes a wide range of boats feel instantly more “alive”: this Yamaha Fourstroke F90XB2 outboard in Yamaha Pearl White. It’s an engine-only listing (no boat attached), ready to be matched to the right hull and put to work.
With 90 horsepower (67.2 kW) at 5500 RPM coming from a 1.8L (1832cc) in-line 4-cylinder platform, this Fourstroke delivers the kind of confident, usable torque that fits perfectly on many 17–20 ft class rigs—think aluminum fishing boats, bay boats, center consoles, pontoons, and utility skiffs that want strong midrange punch without jumping to a heavier, thirstier power class. The 2.15:1 gear ratio helps turn propeller thrust into solid hole shot and steady pull, whether you’re bringing the bow down onto plane or holding speed with a load of passengers and gear.
Because it’s fuel injected and designed to run on regular gasoline, it’s built to be easy to live with day-to-day: smooth starts via electric start, and efficient running in the RPM band you actually use. The full-throttle operating window of 5000–6000 RPM gives you flexibility to prop for your hull and typical payload, aiming for that sweet-spot cruise where four-stroke efficiency shines and the ride stays relaxed.
It’s also made for real marine conditions. Water (open loop) cooling keeps temperatures in check, and it’s explicitly salt water capable—great news for coastal boaters who demand corrosion-ready hardware. Yamaha’s built-in visual/audible alert system and emergency RPM reduction add another layer of confidence when you’re far from the ramp.
Rigging-wise, this F90XB2 is set up for a 25-inch shaft and remote steering control, with power trim to dial in running angle for changing chop, load, or speed. It also brings practical onboard power with a 35-amp alternator to help support electronics, pumps, and accessories.
Dry weight is a manageable 362 lbs (164 kg) for its class, making it a smart choice when you want strong performance without over-burdening the transom.
Ask us about warranty coverage for this new Yamaha outboard and we’ll walk you through the details, plus help you confirm shaft length, prop selection, and best-fit applications for your hull.
