How much horsepower does the Yamaha XTO Offshore produce?

The Yamaha XTO Offshore produces 450 horsepower with its 5.6L V8 engine and combustion chamber. The power comes from a 32-valve DOHC powerhead, which uses direct injection instead of mixing fuel upstream.

The five-pump fuel system can safely spray fuel at high pressures of up to 2,900 PSI, maximizing power and efficiency. The result is stronger combustion, impressive torque, and better fuel economy at cruise.

Is the Yamaha XTO Offshore good for offshore fishing boats?

Yes, this offshore outboard was designed specifically for offshore use in vessels such as fishing boats. It delivers high torque, precise handling and steering inputs, and dependable performance for large center consoles and sport fishing boats.

The award-winning Phase Angle Control Charging system keeps your displays and stabilizers running strong across lengthy outings. You can stay on the water with extreme control longer, so you have more time for sport.

Does the Yamaha XTO Offshore feature electric steering?

Yes, the Yamaha XTO Offshore includes integrated electric steering. This improves the maneuverability of the engine while eliminating some of the rigging complexity of traditional hydraulic systems. You won't have to worry about maintaining pumps, hoses, or fluids with this outboard.

Plus, it's a great fit for Yamaha's Helm Master EX boat control system, which adds full joystick maneuverability, autopilot functions, and automated fishing modes.

What fuel does the Yamaha XTO Offshore require?

The Yamaha XTO Offshore 450HP was designed to operate on 89-octane gasoline. Using this type of fuel will help you get more performance out of every gallon, adding up to meaningful savings over time.

Other upgraded touches throughout the motor include iridium spark plugs and quad thermostats to extend the lifespan of key components between service visits to RJ Nautical.
