Mercury 135 HP Fourstroke

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.

The compact 135hp FourStroke EFI has a 3.0-litre, 4-cylinder in-line configuration, is low weight, has fewer moving parts, and has been designed to be incredibly reliable and durable – ready, willing and able to handle work in any conditions.

Its 4.9 inch (12.5cm) gearcase housing is built to handle higher horsepower, but thanks to its ultra-efficient hydrodynamics this larger housing doesn’t increase drag.

Maintenance free valve train for life.

Its focus mount system, which situates the mounts farther from the powerhead, significantly reduces mount temperature and significantly increases mount durability.

Its lightweight thermo-bonded top cowl provides for long-life, a watertight seal and easy access.

A high grade steel is used to produce its balance shaft gears.

Of course, like many of Mercury’s latest FourStroke models, the new 135hp FourStroke EFI can be rigged with the full suite of Mercury SmartCraft gauges and Mercury’s innovative BigTiller system.
