Product catalog summary

Technical Specifications
Yamaha introduces two new 9.9hp Four Stroke models: F9.9F and FT9.9G. Both models feature a 4-stroke, 2-cylinder in-line engine with SOHC, a displacement of 212cm³, and a prop shaft output of 7.3kW (9.9hp) at 5500rpm. The full throttle rpm range is 5000–6000rpm, with an engine idling speed of 1050 +/- 50rpm. The compression ratio is 9.46, and the fuel induction system uses one carburettor. The lubrication system is wet-sump with an oil pan capacity of 0.8 litres. Maximum fuel consumption is 3.9 litres per hour at 6000rpm. The ignition system is CDI Micro-computer, with manual or electric starting options. The alternator output is 12V - 6A, and the steering system can be a tiller handle or remote control. The gear shift includes F-N-R, and the trim and tilt system offers manual/power tilt with shallow water drive. The exhaust system is through the propeller hub, and recommended boat transom heights are S: 381mm, L: 508mm, X: 635mm. Dry weights are 39.9kg for F9.9 and 44.3kg for FT9.9.

Features and Benefits
The F9.9F and FT9.9G models are compact, economical, and quiet, making them ideal for users transitioning from 2-stroke to 4-stroke engines without adding bulk. They offer power, performance, and portability, with features like a watertight cowling, 6 Amp output alternator, front control, large handy grips, and a single operation steering friction. The engines are designed for reliability and durability, with a strengthened waist drive shaft to absorb impacts. They are economical, with advanced combustion techniques, and meet EU marine exhaust emission standards. The labyrinth exhaust system ensures quiet operation, and the blow-by gas reburning system ensures clean emissions. The models offer convenience with various control, starting, and tilt systems, as well as different shaft lengths and propeller options.

Design and Innovation
The FT9.9G High Thrust version features a higher gear ratio and a Dual Thrust propeller for extra thrust and stopping power, suitable for heavier boats. It includes a long, multi-function tiller handle with front-mounted engine controls for ease of use. Both models have an enhanced 212cc aluminium block and new propellers for smooth, reliable power and impressive torque. The engines are equipped with a CDI Micro-computer, blow-by gas reburning system, and a labyrinth exhaust system for optimal performance and environmental compliance.
