NAMJet Advanced Marine Water Jet Propulsion

The company’s advanced marine propulsion systems provide thrust, durability and speed across a wide variety of commercial, military, and workboat applications.

NAMJet’s line of high-thrust marine jets offer the flexibility of full customisation, while retaining the rugged durability to withstand the most brutal conditions imaginable at speeds of up to 35 knots.

Full-efficient and cost-effective water jet propulsion packages

NAMJet water jets use mass flow designs to pump large volumes of water at relatively low-revolutions per minute (rpm) to provide exceptional thrust while minimising cavitation.

Moving larger volumes of water at lower rpm increases fuel-efficiency and reduces overall horsepower requirements, which allows builders to purchase smaller, more cost-effective engine packages.

Impeller clearance of high-speed jets for abrasive water vessel operation

NAMJet products feature two-to-three times the impeller clearance of competitive high-speed jets, allowing operation in abrasive water without performance deterioration or fouling damage by debris.

NAMJet products enable customers to operate in the harshest conditions.

Multiple lines in the water situations, where a rotating shaft can quickly cause a line to get wrapped around a jet’s shaft, can be dangerous. NAMJet’s optional Tube Protection System eliminates the exposed rotation shaft to maintain vessel operability and ensure crew safety. NAMJet also offers an optional knife system on the aft section of the intake, which severs the line should it become stuck.

Engaging marine jets before entering the water for launch and recovery operations

When launching a workboat from a larger vessel, it is imperative that the smaller craft can escape the larger vessel’s suction and motor away as quickly as possible, especially in environments heavily laden with debris.

To ensure swift launch and recovery operations, NAMJet offers an optional grease-lubricated aft bearing system that enables the jet to run in dry environments. Dry-starts allow operators the opportunity to engage their jets prior to the vessel entering the water.

Flexible jet design and multiple transom configurations

NAMJet’s unique design simplifies installation by welding directly into the hull, making the jet part of the vessel’s structure, and eliminating the need for transition ducts or transom plates.

NAMJet offers the flexibility of multiple transom configurations on-board steel, composite, and aluminium-hulled vessels.

When a manufacturing partner needed a specialized propulsion package for its fast-response workboat, NAMJet engineers custom-designed a "twin-pack" of TJ431HH water jets to create a single, easy-to-install unit that slid easily into the unique hull.

Another shipbuilder came to NAMJet seeking exceptional stability, high forward thrust, and superior reverse thrust, for its newest vessel, a worldwide support platform for oil and gas industry seismographic research.

The company received twin TJ-381HH water jets matched to dual 295hp diesel motors to propel the 31ft, 7,100kg craft to top speeds of 28k, while providing 2,900kg of bollard pull. To date, the company has seen a three-fold increase in reverse thrust since switching to its NAMJet propulsion system.

Low-emission water jets ideal for shallow reefs and aquaculture areas

Environmental responsibility dictates that propulsion systems must be more efficient in order to reduce fuel consumption and emissions, while minimising damage to the fragile marine habitat.

NAMJet has made significant design changes over the years to respond to environmental concerns.

NAMJet water jets provide the highest thrust-per-horsepower at the lowest rpm in the industry. The net result is less fuel burn, lower emissions and diminished impact on the marine environment when operating over shallow reefs and in aquaculture areas.

Marine water jets from the US for worldwide distribution

NAMJet is a global company, with multiple sales channels worldwide; however, every NAMJet water jet starts its journey at the company’s 50,000ft² production facility in Denver, Colorado, US.
