Yamaha F25SWTC 25HP Outboard Motor – Remote Mechanical, Electric & Manual Start, 15″ Shaft (Scratch & Dent)
The Yamaha F25SWTC is a premium remote-controlled version of Yamaha’s award-winning lightest-in-class 25HP four-stroke outboard. Weighing approximately 141 lbs with the 15″ short shaft, it features a compact 432cc SOHC inline 2-cylinder powerhead with battery-less Electronic Fuel Injection (EFI) for easy, reliable starting, crisp throttle response, and excellent fuel efficiency on regular unleaded (87+ octane).
This model (F25SWTC) is rigged for remote mechanical controls, making it ideal for boats with consoles, center steering stations, or dual-station setups on small fishing skiffs, jon boats, inflatables, tenders, and utility craft. It includes both electric start and a built-in manual pull-start backup through the cowling for added redundancy. The power trim & tilt (PTT) system provides effortless shallow-water operation, beaching, and trailering — a major upgrade over manual-tilt remote models.
Key engineering highlights include Variable Trolling RPM capability (when rigged with compatible controls), a 16-amp alternator for powering electronics, built-in carry handles, resting pads for stable horizontal storage, an external freshwater flush port, and Yamaha’s legendary corrosion resistance. The wide-span mounting system and through-prop exhaust deliver smooth, quiet operation with strong low-end torque.
This Scratch & Dent unit has only minor cosmetic imperfections with zero mechanical issues — offering exceptional value on a modern, lightweight 25HP outboard while still qualifying for full manufacturer warranty coverage. Boaters and dealers consistently praise the F25 series for its portability, reliability, easy maintenance, and class-leading power-to-weight ratio.
Whether as a primary motor on a small vessel or a versatile auxiliary/kicker, the Yamaha F25SWTC combines remote convenience, modern EFI technology, and proven durability for hassle-free performance on the water.
