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 VF115 incorporates larger intake and exhaust valves which enhance response, efficiency and mid-range torque.
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.
The direct ignition system with a plug cap and an ignition coil provides higher reliability and increased performance.
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.
Multi-Point Electronic Fuel Injection
The Multi-Point Electronic Fuel Injection (EFI) system, injects the right amount of fuel into the combustion chamber at the optimum timing, for ‘first-time, every-time’ hot and cold starting, improved fuel efficiency, excellent throttle response.
The crankshaft design is offset 5mm from the centre of cylinder for more efficient transfer of power to the crankshaft.
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
Yamaha’s variable trolling control allows 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.
