Exceptional Performance

The “modern” WaterJet Propulsion System was invented in New Zealand by Bill Hamilton in the 1950s and many of the industry's advances have come from New Zealand engineers.

Jet Boat Innovation Advances

For more than 30 years Scott WaterJet has been at the leading edge of development in WaterJets and Jet Boat performance.

Konrad Scott

In 1995 our Founder Konrad Scott began building WaterJets for the new sport of Jet Sprinting. Scott WaterJets quickly became the benchmark for the Jet Sprint World Series.

Scott WaterJets quickly developed a reputation for being rugged and ultra-reliable.

Early Scott WaterJet innovations were hand-made with super-efficient impellers which could reach up to 6,900 revs - enabling higher flow and higher pressure through the pump, interchangeable nozzle inserts, an easy clean grill system, removable front impeller housing, etc.

The Scott WaterJet Trim Nozzle

In 2006 Scott released a patented trim nozzle - a massive advance for jet boating - offering dramatically better boat handling, higher speeds and better fuel economy.

In 2007 Scott WaterJet moved to a 12,000 sq ft complex in Winchester, New Zealand

IN 2018 the Scott 9.1” Two-Stage with Trim was released

In 2018 Scott released the 9.1” (231 mm) Two-stage Waterjet complete with a Trim Nozzle to meet the demands of the modern jet boater to the market. The 912 was designed specifically to harness the increased torque and Horsepower of modern high revving V8’s. And to meet the thrust requirements of the larger jet boats of North America. Additionally, the footprint makes a cost-effective retrofit for the most common single-stage overpowered waterjet in the jet boat industry. Allowing owners to upgrade their power plants and install a superior performing WaterJet that allows them to harness the full capability of their engine.

Early 2019 the Scott 852x Launches

Early in 2019 after receiving some great feedback from a local New Zealand jet boat company Scott WaterJet launched there 852x Waterjet which recognises the benefit of having a WaterJet like the 912 that can be retrofitted into an existing footprint but better matched the modern V8 engines in jet boats that typically had 8.5” single stage units. The 852x provides an engine and performance upgrade to many existing jet boats. Additionally, the 852x accommodates a close-coupled drive line. If the jet boated won’t to go even bigger with there engine in the future the 852x can be easily retrofitted to the 9.1” Scott 912.

A move to Dunedin and Outsourced Manufacturing in 2020

In a local engineering collaboration, Scott Waterjet units are now made entirely from a Dunedin supply chain.

The castings were made at Giltech Precision Castings, machined along with mechanical and hydraulic components at United, and the largest parts sent directly across the road to FARRA Engineering.

Once machined, castings were sent a few doors up the road to Escudo for powder coating, before final assembly and testing at United.

Scott Waterjet operations manager Gareth Turner said United’s production capability and capacity was ‘‘far beyond’’ what the company would have been able to invest in had it set up its own facility.

Importantly, the units that we deliver to our customers are at the highest level due to the high-quality machining, the first-class QA process of United Machinist, and the final assembly / QA of the Scott WaterJet team.
