The Outback Boats Extreme 38 Package is the perfect choice for traversing rocky rivers and shallow waters. Boasting a design that lets you navigate small and large rivers, lakes, and even the sea, this boat offers the best of all worlds for the adventurous spirit.

The Extreme 38 SIB (soft inflatable boat) Hull is 3.8m long and is fitted with a 30hp 2-stroke tiller.
Manufactured in New Zealand from heavy duty polyurethane fabrics, constructed with high frequency welding.
Our materials selection and manufacturing techniques come from 30 years of experience manufacturing white water rafts for the private and tourism sectors along with a number of other marine applications. A lot of these application are high abrasion, impact and UV exposure with a number of the commercial rafts running multiple river trips per day and being left out in the elements 24/7.
From this experience we have been able to select the most robust and UV resistant fabrics to produce an inflatable hull that will far out last anything else available on the market.
Our Inflatable Hulls were developed from extensive prototyping, river impact and abrasion testing. We have created a robust boat with great performance characteristics.
The hull has a Materials and Workmanship warranty of 3 years.
Standard features include:
- Welded Ibeam floor construction.
- Variable dead rise hull which runs super shallow but has softer ride in the chop and white water. Has better tracking and trim than our competitors constant dead rise hulls.
- Increased cornering grip, our hulls have by far the most cornering grip in the SIB inflatable jet boat market.
- Safety valve fitted to floor
- Welded main tube and top tube construction.
- Two padded bench seats that bolt in to our position adjustable rails.
- Foot pump.
- Patch kit.
- Kick up limit rope.
- Extended fuel line mounted to boat which allows you to run the fuel tank at the front or rear of the boat.

- Packed down dimensions 1.25m x 0.75m x 0.46m.
- Hull weight 55kg, 121 lbs
- Heavy duty transport bag
Please note the front inflatable passenger seat shown in the image is sold seperately.


The Ultimate Material Guide
Discover why Polyurethane is the superior choice for your inflatable jet boat

- Better UV resistance than PVC
- Porous surface gets dirty easily
- Still contains chlorine
- Second-best option
- Medium stab & abrasion resistance
🏆 Polyurethane
★★★💪 The Ultimate Choice
- 4x stronger abrasion resistance than Hypalon
- Superior UV & chemical resistance
- Environmentally friendly (no chlorine)
- Easy to repair
- Longest lifetime
- Superior stab & abrasion resistance
