5 reviews for Yamaha 15hp 15″ Shaft | F15SEHA
Bought this for my tender boat, and the 15″ shaft fits like a glove for shallow launches. Yamaha’s twin-cylinder design delivers smooth torque right from idle—great for quick getaways. Electric start is reliable every time, and fuel efficiency is class-leading; full day out and plenty of gas left. Quiet vibes make it family-friendly. At this weight, it’s easy to store—love it!
The F15SEHA is a lightweight champ on my 12-foot inflatable—117 lbs makes solo mounting a snap. Electric start fires up instantly via CDI, no pulls needed even in damp conditions. Sips fuel with that single carb setup; trolled for hours on under a gallon. Hits 16 mph with two aboard, super quiet for sneaking up on panfish. Perfect short-shaft portable for tight spots!
Mounted the F15SEHA on my small aluminum pram, and it’s transformed my pond fishing. CDI ignition ensures easy starts, and the low-end power planes me fast with gear. Super efficient on fuel, about 5 mpg cruising. The tiller is ergonomic, but wish the trim range was a tad wider for beaching. Still, reliable and quiet—solid 4-stroke choice.
Ideal kicker for my canoe in shallow creeks—the 15″ shaft avoids dragging. Starts on the button every time, thanks to CDI microcomputer smarts. Fuel sipping is unreal for long drifts, and it’s whisper-quiet to not spook the trout. At 117 lbs, trailering is effortless. Yamaha’s build quality means zero worries—best portable I’ve owned!
This Yamaha 15hp is a powerhouse for my 13-foot jon boat. Electric start with no battery drama (just add your own), and the carb system keeps it running cool and clean. Trolled bass all morning on minimal gas, hitting precise low speeds. Pushes 18 mph solo—impressive torque for the size. Lightweight and corrosion-resistant; ready for more seasons.
