Mercury four stroke outboard motors are incredibly powerful and efficient and suit a wide range of applications.
Crafted with less weight and higher displacement, they generate heaps of bottom end torque and immediate power.
Because they don’t have to work as hard as engines with lower displacement, they can hit plane faster and accelerate harder whilst providing optimal fuel efficiency at cruising speed.

Designed to provide reliability and durability, no matter what is thrown at it, Mercury’s new compact 135hp FourStroke also delivers tremendous performance and outstanding fuel efficiency.

The model has been created and developed specifically from the feedback given to us by Australian and New Zealand consumers, dealers and boat builders, and sits nicely between our new 2.1L 115hp and the well proven and hugely successful 150hp FourStroke platforms.
