Description
The Mercury 3.5MH is a 3.5HP four-stroke outboard motor built for Australian boat owners who need dependable power on the water. Fitted with a 1-cylinder, air-cooled powerhead displacing 85cc and running a carburettor fuel system, this short (15″) shaft outboard is set up with manual start and tiller control, giving you a straightforward, reliable setup whether you’re heading out for a weekend fish or a longer day on the water.
At 18kg, the 3.5MH 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 inflatable tenders, small jon boats and as an auxiliary motor for sailing yachts, and is finished in Mercury Black to match Mercury’s current outboard line-up.
Key features:
– Ultra-lightweight, easy-carry design ideal for tenders, inflatables and small aluminium dinghies
– Simple tiller handle steering with integrated fuel tank for hassle-free setup
– Reliable manual pull-start with smooth, low-vibration four-stroke running
– Backed by Mercury’s standard recreational outboard warranty coverage in Australia
– Compact enough to store in a boot or under a seat between trips
