Description
The F25LWTC is built around Yamaha’s 432cc two-cylinder powerhead with electronic fuel injection and battery-less EFI capability, meaning the fuel injection system doesn’t require a battery to operate . This translates to quicker starts and more reliable operation whether the engine is cold or has been sitting for weeks .
The CDI Microcomputer Ignition System continuously monitors throttle position, engine speed, and atmospheric conditions to precisely adjust ignition timing for optimum performance, economy, and power under all conditions . The streamlined intake manifold with long tracks and smoother airflow provides reliable and responsive power with outstanding fuel efficiency .
Yamaha’s Phaze Five™ electro-deposited anti-corrosive paint system, combined with their proprietary YDC-30 alloy, provides a tough, five-layer barrier against corrosion — standard on all Yamaha portable four-stroke outboards . The Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life .
The 16-amp alternator is the most powerful in this class, providing ample charging capacity for onboard electronics like fish finders, GPS, and radios . The Variable Trolling RPM Switch (VTS) allows precise trolling speed adjustment in 50 RPM increments — an essential feature for serious anglers .
The Engine Warning System protects the outboard with overheat protection, low-oil-pressure warning, over-rev limiter, and start-in-gear prevention for enhanced durability and safety .
