Description
Key features
DEC models can be equipped with the new bolt-on Helm Master® EX Digital Electric Steering as well.
Thrust Enhancing Reverse Exhaust (TERE) keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpm when in reverse. This means the prop bites only clean water, resulting in outstanding reverse thrust and control to back down on fish.
Faster, easier engine tilting with Yamaha’s exclusive TotalTilt™ function, which allows complete tilt up from any position with a simple push of a button.
Stunning new looks meet proven performance to compliment and complete even more premium boats.
