2010 Ozamphibian Platypus review

It’s certainly not every day you see a swimming Suzuki. Meet the Platypus.

2010 Ozamphibian Platypus review

Built around a Suzuki Jimny and powered by that vehicle’s standard 1.3-litre petrol engine, it’s only when you clamber over the tall sides of the vehicle – sorry, boat – that you have any inkling that this little amphibian, called a Platypus, is, or was, a Suzuki.

Built by Ozamphibian, based in Tara, Queensland, this example we found was playing in the Murray River, far removed from its normal haunt of Moreton Bay.

The standard Suzuki chassis has been encased in a fibreglass hull, so while the outside of the vehicle may be completely unique, the interior is standard Jimny. There is only an extra lever to contend with and that is to engage the custom-made Hamilton-style water jet drive.

The power to drive the jet comes off the transfer box, while steering in the water is still via the front wheels – it seems to work surprisingly well. A twin propeller arrangement can be fitted if a customer orders a craft that is destined to spend long periods in the water. Twin props aid economy but reduce speed.

All up weight is 1100kg and, being a boat of sorts, it does have a bilge pump capable of pumping around 3785 litres an hour, if needs be. Top speed on land is over 100km/h, but the off-road ability is not quite as good as the original Jimny. On water the craft has a top speed of seven knots, or around 12-13km/h.

The Platypus has a surprising amount of freeboard, and from what we could see, as it was tested in a two-metre swell, it handled the tough conditions with aplomb. There is also a rough water version that, when the hatches are closed, takes on the qualities of a small submarine.

Now, if you want to get afloat in something a little different, or for more information on the Platypus, contact Sean O’Donnell, phone (07) 4669 4022.
