Description
|
For those who want more, the answer is here. Featuring the same 5.6-litre big-block displacement and long list of features as the XF425, the all-new XF450 improves upon the powerful platform that changed the offshore boating game. With more charging, convenience, functionality and horsepower, the Yamaha XF450 will make a splash.

Highlights
 HELM MASTER EX COMPATIBLE
Helm Master is a fully integrated boat control system that allows captains of large offshore boats to truly master their boating experience. This system is now available in Canada through select OEMs on new boat packages equipped with Yamaha Digital Electronic Control models from 150hp to 450hp.
|
 INDUSTRY-EXCLUSIVE INTEGRATED FULLY ELECTRIC STEERING SYSTEM
With no hydraulic lines or linkages, the integrated steering system responds more quickly than conventional systems to steering inputs. Additional benefits include reduced power consumption, clean rigging and a very orderly bilge area.
|
 IN-WATER GEAR LUBE CHANGE SYSTEM
Boats powered by the V8 XTO Offshore need go no further than the dock for a lower unit service, thanks to a unique gearcase lubricant exchange system that allows maintenance in the water.
|
More Charging Power
To help meet the extreme electrical demands of today’s larger boats, the Yamaha XTO Offshore 450 features a three-phase, simultaneous charging system that delivers an incredible amount of net amps at lower rpm, where it’s needed most. Using Phase Angle Control (PAC) componentry and a super-strong magnetic field, XTO Offshore 450 models produce up to 96 net amps per engine in neutral. That’s plenty of power for today’s popular, high-demand devices like gyro stabilizers, air conditioning, sound systems and more.

KEY FEATURES
|
Key_Features
- Even more charging power: Using Phase Angle Control (PAC), which adjusts the intensity of the stator’s magnetic field, XTO Offshore 450 models produce up to 96 net amps per engine in neutral. The new XTO Offshore provides more power for today's popular on-board, high-demand devices like gyro stabilizers, air conditioning, sound systems, and more, all while keeping starting batteries constantly charged.
- Highest compression ratio in an outboard: Get more "bang" from every spark with a 12.2:1 compression ratio: better efficiency, more power and incredible throttle response.
- Plasma-fused sleeveless cylinders: This micro-textured surface is 60 percent harder than steel, yet significantly lighter and thinner, increasing displacement without increasing the size of the powerhead. Other benefits include reduced friction, faster heat transfer and improved fuel economy.

FEATURES AND BENEFITS
|
Features_&_Benefits
HIGHEST COMPRESSION RATIO IN AN OUTBOARD
Get more "bang" from every spark with a 12.2:1 compression ratio: better efficiency, more power and incredible throttle response.
|
EVEN MORE CHARGING POWER
Using Phase Angle Control (PAC), which adjusts the intensity of the stator’s magnetic field, XTO Offshore B models produce up to 96 net amps per engine in neutral. And since the electric steering only requires power while moving the engine, there is more power to spare while idling or trolling - when boaters need it most!
|
PLASMA-FUSED SLEEVELESS CYLINDERS
This micro-textured surface is 60 percent harder than steel, yet significantly lighter and thinner, increasing displacement without increasing the size of the powerhead. Other benefits include reduced friction, faster heat transfer and improved fuel economy.
|
EXTREME XTO OSTM PROPELLERS
Yamaha's new family of XTO OS Propellers are made to complement the torque potential of the Yamaha XTO, working as an integral part of a system to produce massive thrust in both forward and reverse. With new stainless steel material, they are also more resistant to corrosion and surface discolouration.
|
MULTI-PART COWLING SYSTEM
The cowling and engine covers on the XTO are in multiple pieces for easier access to specific parts of the powerhead and midsection. These are integrated using captive fasteners and a special one-piece seal.
|
IN-BANKTM EXHAUST
Yamaha's exclusive In-Bank exhaust improves flow with intake tracks entering the cylinder head from both sides of the powerhead, allowing space for exhaust gases to have a direct route to the lower unit and out the propeller hub.
|
THRUST-ENHANCING EXHAUST ROUTING
Below 2500 rpm, engine exhaust is directed away from the propellers for "cleaner" water and added bite in both forward and reverse, maximizing command and control at lower speeds.
|
WIDER TILT RANGE
At full extension, the XTO Offshore has been engineered to allow the entire motor and lower unit to be raised completely out of the water for added convenience.
