2027 Yamaha Four Stroke High Thrust T9.9XPB
Description
Bring dependable push and dockside confidence to your next rig with this 2027 Yamaha Four Stroke High Thrust T9.9XPB in classic Yamaha Gray. This is an engine-only listing—perfect if you’re repowering a small cruiser, sailboat, tender, or a heavier displacement hull that wants thrust you can feel, not just a horsepower number on paper.
Built as a High Thrust outboard, this 9.9 bhp (7.4 kW) Yamaha Fourstroke is tuned to deliver strong low-end torque where it counts—getting a load-moving hull up to an efficient cruise and maintaining control in current, wind, and tight marina lanes. The 2.92:1 gear ratio is a big part of that “dig in and go” attitude, translating the engine’s power into confident prop bite for boats that need more push per rpm than a lightweight skiff.
Under the cowl is a compact 212 cc in-line 2-cylinder design with SOHC and 4 valves (2 per cylinder). It’s engineered to run in a practical full-throttle range of 5000–6000 rpm, with rated output at 5500 rpm—a sweet spot for smooth, steady cruising and sensible fuel use on regular gas. Water (open loop) cooling helps it stay consistent on long runs, and it’s salt water capable for coastal duty.
Convenience comes standard: electric start for easy launches, power trim to fine-tune running angle, and remote steering control for clean integration at the helm. The 25-inch shaft is ideal for many sailboat and kicker applications where extra transom height and improved control in chop matter. At 114 lb dry, it’s substantial enough to feel robust without being a hassle for most repower projects.
For peace of mind, Yamaha’s built-in visual/audible alert system and emergency RPM reduction help protect the engine if something needs your attention. Add in a 6-amp alternator to support essential onboard charging, and you’ve got a hardworking, confidence-inspiring outboard that’s ready to earn its place on your transom. Warranty coverage is included when applicable—contact us for the details for this new engine.
