F75
With its advanced 16-valve, four-valve-per cylinder, Single Overhead Camshaft (SOHC) design and large 1.8 Litre displacement, the F75 delivers the ultimate combination of unbridled power and refined performance for the mid-range outboard market. The F75’s lightweight powerhead configuration, refined shaping of the combustion chamber and lean fuel burn technology, means this outboard is extremely fuel efficient, while also delivering an exceptionally smooth and quiet riding experience. This outboard is compatible with Yamaha’s comprehensive range of Command Link gauges and NMEA2000 compliant, meaning you can share engine information with third party multi-function displays, GPS and fish finder systems.
Technical Specification
Larger 81mm Cylinder Bore The previous-generation F90 used a 79mm cylinder bore, in the next-generation F90 the cylinder bore size has been increased from 79mm to 81mm which provides more efficient power delivery. A larger valve has been used for increased transfer efficiency for both intake and exhaust.
Offset Crankshaft The crankshaft design is offset by 5mm from the centre of the cylinder. This innovative design decreases internal friction and promotes a more efficient transfer of power to the crankshaft.
One-Piece Cowling This engine features a new outer cowling design with an intake air drain system, to easily and efficiently drain away any water that enters the cowling during normal engine operation. Incoming air is routed through a labyrinth of passages that help trap and drain water before it enters the engine’s intake, for maximum reliability.
Single Bore Throttle Body The 60mm wide single bore throttle intake minimises intake resistance and provides first-rate response for brisk-acceleration and high-speed operation.
Single-Ram Power Trim and Tilt Unit The compact and light-weight single-ram power, trim and tilt (PTT) unit and bracket have been developed exclusively for this engine.
Variable Trolling Control Yamaha’s variable trolling control allows the skipper to precisely adjust the engine’s idling speed from 550 to 1000 RPM in 50 RPM increments. The ability to finely tune the trolling speed allows fisherman to perfect their lure presentation when chasing different species of fish.
1832cc 16-Valve SOHC Marine Engine With its increased 1.8 litre capacity and single overhead camshaft, four-valve per cylinder design, the new F90 delivers improved acceleration and power-to-weight performance.
ECM Micro-Computer Control This outboard is controlled by an advanced microprocessor Engine Control Module (ECM), which receives inputs from six major sensors located throughout the engine. This information is used to ensure the engine runs at peak performance, by delivering the right fuel/air mixture to each combustion chamber.
High Output Alternator A 12-Volt 35-Amp high-output alternator ensures that power is always available to start the engine, even after long periods of idling or running at low revs. This not only provides extra starting power, but delivers sufficient power to run the wide array of on-board electronic devices used in modern boating.
