16-Valve DOHC Direct-Action In-Line 4
With 2 intake valves and 2 exhaust valves on each cylinder – and, with twin camshafts, each also driven independently – intake and exhaust efficiency are dramatically improved, optimising fuel use during combustion. The TCI ignition system ensures easy starting, consistency, longer plug life and - ultimately - reliability.
Sleek and efficient cowling design
An attractive appearance is not the only advantage of this purposeful-looking cowling. It is designed to trap and drain water with maximum efficiency, leading to even smoother operation, less corrosion and longer engine life.
Variable Trolling RPM control
This sophisticated system allows you to control low speed operation smoothly and easily, by adjusting your speed in 50 RPM steps at the touch of a switch. Ideal for fishing, or for cruising politely through no-wake zones!
Digital Network Gauges (optional)
All our EFI engines can be linked, via Yamaha's own network system, to a wide range of digital instruments - to help you get the best from your engine. A multi-function tachometer displays RPM, engine hours, trim angle, oil pressure and warning lamps. The combined Speed & Fuel Management gauge shows speed, fuel tank level and economy data.
Micro-computer ECM (Engine Control Module)
This reliable micro-computer is the 'brain' of your Yamaha engine. It constantly monitors all data inputs and settings, to ensure smooth running and optimised ignition timings – as well as automatically activating the warning and protection systems. A handy access port lets authorised Yamaha dealers easily diagnose any problems.
Yamaha Customer Outboard Protection (Y-COP) option
The optional Y-COP immobiliser system is simple, easy to use and highly effective – a neat and simple remote control locks and unlocks the engine at the push of a button. This prevents your outboard engine being taken for any unauthorised joyrides, offering you peace of mind when leaving your boat unattended.
Counter-rotating propeller model
A standard twin-engine installation (both propellers turning clockwise) tends to pull the boat towards the port side, making steering more difficult, especially at higher speed, so the 150hp is also available with a counter-rotating propeller. When fitted alongside a standard propeller model, the driver has perfect ‘neutral helm' control .
Optional Dual Battery Charging System
The special Dual Battery Charging System allows two batteries to be charged simultaneously, ensuring that plenty of power is available for engine starts – even after long periods at low RPM or when using multiple accessories.
