Jet-Tech Propulsion, an Outdoor Network LLC company, through a partnership with Diesel Outboards LLC, introduced a new ultra-high-performance waterjet designed for an outboard diesel engine at the 2021 International WorkBoat Show.

The partnership is in collaboration with the Swedish outboard engine manufacturer OXE Marine AB (OXE).

Jet-Tech is a single stage compact high performance waterjet which combines mixed-flow properties within an axial design build, with a hybrid stator for high torque diesel outboard engines.

The Jet-Tech waterjet performance is equal to or better than propeller versions and is matched 1:1 to the unit horsepower-driven prop outboard, a level of achievement that has never been reached in any waterjet product to date, according to Diesel Outboards’ President Douglas Natoce.

“It was a substantial investment,” he said from the floor of the Morial Convention Center in New Orleans as more than 700 exhibitors prepared their booths for the opening of the show the next day, “but we built the first one and the data told us we had what we were hoping for.”

Natoce said the approach combines the key benefits of high-speed efficiency with cavitation margins at lower speeds and high load conditions that Diesel Outboards, Jet-Tech, and OXE Diesel think are excellent.

The waterjet launch builds on OXE’s transformation of the high-horsepower, high torque diesel outboard market enabled by its OXE Diesel range.

“The Jet-Tech waterjet performance is equal to or better than propeller versions and is matched 1:1 to the unit horsepower-driven prop outboard,” said Natoce. “This level of achievement has never been reached in any waterjet product to date.”

The new Jet-Tech fits every OXE Diesel model manufactured. “By using advanced proven waterjet engineering and design capabilities, augmenting the

innovative OXE Diesel design, we completely redefined outboard motor propulsion and performance,” said Natoce. “The Jet-Tech unit is designed to

grow with our expanding product line as it is a fully scalable product. The patented design will expand into the vertical shaft diesel/gas outboard waterjet applications and inboard waterjets.”  

“The Oxe Diesel Outboard was originally designed for the commercial and government users and is now expanding into other marine markets. We have seen the offshore center console community wanting greater range, better fuel economy, mega yacht tenders needing SOLAS certification as well as the need for the removal of gasoline bunkering, while the commercial and government users need the safety of diesel, and the commonality of global fuel standardization,” said Magnus Grönborg, OXE Marine AB’s CEO. “They all want and need torque to move the larger and heavier vessels that were traditionally powered by gasoline outboards and inboard engines but many desire the choice of diesel outboards and now, combined with Jet-Tech Propulsion LLC ́s capabilities, they can also get diesel outboards with [a] waterjet.”
