This engine is all about balance—in that completely unapologetic, “hold my drink” kind of way. But with torque this strong, it’s probably best to let someone else hold the drink. Yes, the engine delivers breathtaking acceleration and impressive top speed, but it’s the low-rpm power that makes all the difference, making manoeuvring feel almost telepathic. Every twist of the throttle is an unmistakable reminder that you now own the water—the rest of the marina can do nothing but watch.

Power has never looked this effortless. Premium design and a sculpted cowling with efficient water drainage create a clean, modern silhouette that enhances the look of any boat. Discreet? Hardly. It’s a design that says, “I’m here to deliver” before the engine has even started.
Complex manoeuvres, simplified. Helm Master® EX transforms docking, positioning, and low-speed handling into smooth, confidence-inspiring experiences, with joystick control and intelligent integration that make tight spaces feel far more manageable.
Say goodbye to cables and hello to total, effortless control. Drive-by-wire replaces mechanical linkages with smooth digital control, delivering smoother shifting, better throttle response, and easy synchronisation between multiple engines. It’s the difference between simply “driving” and truly “mastering” the boat.
Fuel is delivered with precise accuracy. Yamaha’s EFI system ensures smooth starts, consistent acceleration, and excellent efficiency—providing reliable performance with less hassle and fewer stops for refuelling.
Remove the salt. Extend the life. Simply connect a hose to the front-mounted connection and flush the system without starting the engine. Less corrosion, easier maintenance, and more time for everything else.
Reverse like a king. By keeping exhaust gases above the anti-ventilation plate, TERE ensures the propeller only grabs clean water when reversing, delivering stronger and more precise low-speed manoeuvrability. Combined with the advanced steering systems, docking becomes almost ridiculously easy.
Nordwall Marin finns på det anrika Bosövarvet på Lidingö. Vi har byggt, sålt, reparerat och servat både båtar och motorer ända sedan 1946. På varvet finns det även en tillbehörsbutik och vi har sommarplatser att hyra ut vid våra bryggor..
