Description
The F8SMHB is built around Yamaha’s 212cc two-cylinder SOHC four-stroke engine — a compact, inline design that delivers exceptional speed and acceleration for its size. The engine features a carburetor with acceleration pump for responsive throttle control and a CDI Microcomputer ignition that continuously monitors conditions for optimal performance.
Easy, Reliable Starting: The manual-start F8SMHB features an easy-grip starter knob with a built-in automatic decompression device that releases cylinder pressure during cranking, significantly reducing the effort required for quick and reliable pull starts. An auxiliary prime pump located under the cowling ensures smooth starts even after periods of long storage.
Dual Fuel System for Extended Range: A significant advantage of the F8SMHB is its dual fuel system. It features a convenient built-in 0.29-gallon (1.1-liter) see-through fuel tank, allowing you to easily monitor fuel levels. Crucially, it also includes a switchable connection for an optional external fuel tank (e.g., a 3.1-gallon tank), providing excellent extended range for longer excursions.
User-Friendly Tiller Control: The F8SMHB features a newly designed shorter tiller handle that folds back tighter to the cowl for more secure and compact storage. The handle includes a twist-grip throttle for precise speed control, and its 43-degree steering angle (from center, either direction) provides exceptional maneuverability. The front-mounted shift lever offers clear Forward-Neutral-Reverse operation.
Legendary Yamaha Durability: The F8SMHB benefits from Yamaha’s commitment to durability with YDC-30 aluminum alloy, a 5-stage Phaze Five™ paint process, zinc coating, and high-quality marine-grade stainless steel components — all designed to withstand harsh marine environments. A freshwater flushing system allows for easy rinsing of salt and dirt without running the engine.
The Engine Alert System protects the outboard with visual and audible warnings, plus emergency RPM reduction to help protect the powerhead when conditions demand attention.
