Intuitive, innovative features
High-output alternator
Convenient maintenance
We made maintenance easier with features like colour-coded touch points, an easy-access water-separating fuel filter and an oil filter drip tray, which helps you get the job done with less mess.
Command Thrust gearcase
Designed to sit lower in the water and turn larger props, the available Command Thrust gearcase lifts heavy boats on plane more easily and holds them there at lower speeds without impacting top speed.
Tiller handle
With a range of adjustments, ergonomic controls and the flexibility to be set up for left or right-handed operation, the available advanced tiller puts you in complete command of your adventures.
Electronic Fuel Injection (EFI)
From the moment you crank the engine to the moment you drop the throttle, EFI technology responds with instant power. Surefire starting in all weather conditions. Smooth, efficient acceleration. Maximum fun.
Fourstroke performance
Powerful torque
A high-displacement powerhead generates serious low-end torque to easily power boats on plane. More torque requires less work from the engine, for a longer service life.
Quick acceleration
The single-overhead-cam design delivers sporty acceleration and exciting overall performance from midrange through to top speed.
Hard-working muscle
With an available Command Thrust gearcase and ample torque, 40 to 60hp outboards make easy work of moving heavily loaded boats.
