NAMJet’s advanced marine propulsion systems have set the standard for Thrust, Durability, and Innovation. Designed for a wide variety of commercial, military, and workboat applications, our NAMJet TJ Series line of high-thrust marine jets is tough enough to withstand the most brutal conditions imaginable. NAMJets TJ Series are rated for speeds up to 35 knots, and may be fully customized to meet the standards of the world’s most demanding operators.
The TJ Series unique design simplifies installation by either bolting in or welding directly into the hull to become part of the vessel’s structure, eliminating the need for transition ducts or transom plates. NAMJet’s unique design offers the flexibility of multiple transom configurations aboard steel, composite, and aluminum-hulled vessels.
