Yamaha Customer Outboard Protection (Y-COP) option
Yamaha's unique Y-COP immobiliser system is a simple, easy to use and highly effective option – the neat and simple remote control locks and unlocks the engine at the push of a button. This prevents your outboard engine being taken for an unauthorised joyride, offering you peace of mind when leaving your boat unattended.
Variable Trolling RPM control
Another feature of the optional Digital Network System is the handy button on the tachometer which gives you instant control of the engine RPM - making it simple to adjust the engine speed in convenient steps of 50 RPM between 650 and 900 RPM. Smooth, relaxed cruising is the reward.
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.
SDS (Shift Dampening System)
First introduced for our larger V8 and V6 models, Yamaha's patented Shift Dampener System (SDS) is a great feature that significantly reduces the 'clunk' sound normally associated with moving between gears. A splined rubber hub and aft washer absorb noise and vibration, in a carefully engineered solution that gives smoother, quieter gear shifts.
2.8 litre DOHC 4-cylinder with 16 valves and EFI
This thoroughbred engine delivers excellent combustion efficiency across the RPM range with features like EFI, 4 valves per cylinder and DOHC (Double Overhead Camshafts). In summary, a fine blend of advanced technologies offering exceptional horsepower-per-litre and a high power-to-weight ratio.
Special offset crankshaft delivers a compact design
We designed the 175hp to be ultra-compact and the special offset crankshaft and gear-driven balance shaft are just two of the many technical advances pioneered by our engineers to help achieve that aim. The labyrinth exhaust systems, with their water-sealed outer walls make them exceptionally quiet too.
