Yamaha Outboard’s Reveal of the 5.6L V8 XTO Offshore Engine

At Fish Tale Boats, we are excited to offer a suite of Yamaha motors for all sizes and boats. Last month, Fish Tale’s team had the pleasure of visiting the Yamaha Outboards test facility to unveil the new 5.6L V8 XTO Offshore engine. The new model is Yamaha’s biggest outboard yet, since the company debuted the F350 in 2007. The engine features direct injection, 12.2-to-1 compression, and electric steering.

Highlights of Yamaha’s latest engine model:

  • The first four stroke powerhead in the outboard industry to use direct injection. To improve atomization and increase the effectiveness of the fuel burn, fuel is sprayed at a high pressure directly into the combustion chamber rather than the intake track.
  • To ensure proper fuel flow and delivery even at very high-pressure RPM, the direct injection system has five fuel pumps and allows injection pressure up to 2,900 PSI. The three-stage fuel-pressure system is composed of two fuel pumps within the Vapor Separator Tank that activate at individual RPM.
  • For better efficiency and power, the motor has the highest compression ratio in an outboard at 12.2-to-1, enabled by the piston-cooling effects of direct injection.
  • The integrated electrical steering system with no hydraulic lines or linkages, responds quicker than conventional systems to steering inputs.
  • A two-stage water pump and dual-chamber oil pump, designed to respond to heavy loads; as well as an oversized gear case, hardened gears, and a robust offshore bracket and motor mounts.
  • Improved throttle response and economy, increased service interval, and improved power – the motor’s spark plugs are made from the rare element iridium.
  • Quad thermostats, 2 per cylinder bank – one to help regulate engine temperature, and one to help regulate oil temperature.

The outboard system is designed to push the heaviest offshore boats and yachts, with 5.6 liters of thrust and 425 horsepower. At Fish Tale, we carry Grady-White boats which are one of the highest quality offshore fishing boat manufacturers. We we’re thrilled to feature our Grady-White Canyon 456 as a test at the 5.6L V8 XTO Offshore engine unveiling. The 456 is a re-imagining of a luxury sportfishing yacht, crafted with exceptional attention to detail. The flagship is incredibly spacious, 24,500 lbs. without engines, and is 45-feet long. The Grady White Canyon 456 has the widest beam in its category and is the largest unsinkable boat of its kind.
