Yamaha’s

big gun

Yamaha has upped the ante in

the high horsepower stakes with the

release of its new V8 425 XTO

(Extreme Oshore) outboard.

A

big bore, 5.6-litre, naturally-aspirated engine, the

425hp V8 has been engineered to drive large props

for maximum thrust.

“It opens up a new class of large outboard-

driven boats,” says Matt Walton-Smith, Yamaha

Motor New Zealand’s Marine National Manager. “It delivers a

more reliable, fuel-eicient and very powerful engine solution

for ofshore ishing, pleasure, commercial and tourism boats.”

he big outboard also introduces a range of new technologies.

“Our engineers have developed an industry-irst – a fully-

integrated electric steering system, that has no mechanical

hydraulics or electric pumps. his is combined with our updated

premium CL7 multifunction touchscreen display, advanced

‘drive-by-wire’ throttle controls and Helm Master joystick

docking and positioning, to create a truly efortless boating

experience,” says Walton-Smith.

Yamaha has also developed the irst-ever, four-stroke direct

fuel injection powerhead to deliver a very high compression ratio.

To ensure this massive power translates directly to the water,

Yamaha has designed a large diameter XTO OS propeller. Its

large, bladed surface area delivers extreme thrust for superior

acceleration, cruising and top-end speeds, and complements the

engine’s new exhaust venting technology.

Other features include an oversized gearcase, hardened

gears, a robust, ofshore wide-span bracket and engine mounts,

and proven plasma-fusion technology for increased durability

and a lighter weight.

Running a large 90-amp power generation system, the V8

delivers more than enough punch to run the large array of

electrical devices in today’s modern boats.

Engine care and accessibility have also been improved.

here’s a new in-water gear lubricant change-out system, which

allows the outboard to be serviced while the boat is still on

the water, saving on expensive haul-out costs. he multi-part

cowling system also provides added convenience by allowing

quick and easy access to key parts of the outboard.

Pricing, availability and the XTO’s oicial New Zealand

launch date is to be conirmed. BNZ
