1832cc Four-Cylinder Engine
The 16 valve, 1.8 litre dual overhead camshaft design delivers superior efficiency in the transfer of intake and exhaust gasses throughout the RPM range. The F130 incorporates larger intake and exhaust valves which enhance response, efficiency and mid-range torque.
Electronic Throttle Valve
The electronic throttle valve makes precise throttle movements according to engine temperature and atmospheric conditions, to deliver incredible response, awesome power and exceptional fuel economy.
81MM Cylinder Bore
The cylinder bore size has been increased from 79mm to 81mm which provides more engine torque. A larger valve was adopted for increased transfer efficiency for both intake and exhaust.
Direct Ignition
The direct ignition system with a plug cap and an ignition coil provides higher reliability and increased performance.
Multi-Point Electronic Fuel Injection
The previous-generation F75 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 5mm from the centre of cylinder for more efficient transfer of power to the crankshaft.
Shift Dampener System
Yamaha’s Shift Dampener System (SDS), built into selected Yamaha propellers, delivers smooth and quiet operation when shifting in and out of gear by absorbing the force that is created.
Single Ram Power Trim and Tilt
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
The skipper to precisely adjust the engine’s idling speed from 600 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.
