Mercury 300XL 300HP 4-Stroke Outboard Motor – Long (25″) Shaft, Electric start

Description

The Mercury 300XL is a 300HP four-stroke outboard motor built for Australian boat owners who need dependable power on the water. Fitted with a V8, naturally aspirated, water-cooled powerhead displacing 4600cc and running a electronic fuel injection (efi) fuel system, this long (25″) shaft outboard is set up with electric start and digital throttle & shift (dts) control, giving you a straightforward, reliable setup whether you’re heading out for a weekend fish or a longer day on the water.

At 272kg, the 300XL is engineered to be light enough to handle on the transom while still delivering the torque and acceleration boaters expect from Mercury’s four-stroke range. It suits offshore centre consoles, larger cruisers and twin/multi-engine high-performance rigs, and is finished in Mercury Black to match Mercury’s current outboard line-up.

Key features:
– Large-displacement naturally aspirated V8 powerhead delivers strong torque, top speed and class-leading smoothness
– Digital Throttle and Shift (DTS) for precise, responsive control and effortless docking
– Advanced MidSection (AMS) mounting virtually eliminates vibration for a smoother, quieter ride
– Advanced Range Optimisation (ARO) and a closed-loop fuel system maximise fuel economy
– Premium SmartCraft digital integration for full engine monitoring at the helm
