YAMAHA’S NEW monstrous V8 XTO Offshore, a 425-horsepower, naturally aspirated 5.6L outboard. Looks to be one very impressive engine.  The fact that it has true electronic steering (fly by wire) is amazing.  So are the 17″ props!

The new engine comes in three different shaft lengths – 25 inches, 30 inches and 35 inches. When fitted with a propeller and filled with motor and gearcase oil, the 35-inch XTO weighs more than 1,000 pounds.This engine is designed to take Yamaha to the next level of what they can possibly do with outboard motors within the industry. Yamaha are answering the call for bigger boats with a different platform, a new, big-block 5.6L V8. It’s all about integrating power systems into much larger boats.

New XTO OS propellers are made to complement the torque potential of the Yamaha V8 XTO Offshore. These new propellers produce more thrust in both forward and reverse, using diameters from 16 to 17 1/8 inches.
