Details & Inspection Notes
Pushing water harder at low rpm rather than chasing top speed, the T9.9XPB is Yamaha's high-thrust take on the 9.9 hp, 212cc, two-cylinder portable. A 25-inch shaft and remote mechanical steering mean it is meant for a console and cables rather than a handlebar at the stern, and electric start, power tilt and a dual-thrust aluminum propeller all come standard. Dry weight on this listing is 108 lbs.
Where this trim fits
Owners generally reach for the high-thrust T-series when they need steady pulling power more than speed, which makes it a common kicker motor on a multi-species boat, or the primary motor on a pontoon or houseboat that rewards low-end thrust. Because the lower-unit gearing differs from a standard F9.9, swapping between high-thrust and standard versions later is not a simple parts change.
Before ordering, measure your transom against the 25-inch shaft, and confirm your boat already has the control box and cables a remote-steer motor needs, since this is not a tiller-handle unit. At 108 lbs, most hoists and transom ratings in this class handle it without issue, but it is worth checking rather than assuming.
Questions buyers ask
Does a propeller come with it? Yes, the dual-thrust aluminum prop is part of the standard package.
Is tilt manual or powered? Powered; tilt is built in rather than set by hand.
What's the difference from a standard F9.9? The high-thrust T-series uses different gearing in the lower unit for more low-speed pull, at some cost to outright speed.
What's the warranty? Yamaha backs this engine with a 3-year warranty.
