2022 Yamaha XF425A For Sale

• Highest compression ration in an outboard: Get more “bang” from every spark with a 12.2:1 compression ratio: better efficiency, more power and incredible throttle response.
• Great charging power: The V8 XTO Offshore provides up to 90 amps of total (gross) power. 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 OS™ 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-Bank™ 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 extends 5.4 inches higher out of the water than the F350. The new outboard has been engineered to allow the entire motor and lower unit to be raised completely out of the water for added convenience.
