PROPULSION UPDATE Put To The Tesf: North American Marine Jet's Nomera 14 Water Jet Calm water performance tests have been performed on a Patrol Boat, Riverine, with North America Marine Jet's Nomera 14 water jet and a competing product, according to the manufacturer. The Nomera 14 jet was formerly the Jacuzzi jet. The Jacuzzi/Nomera 14 jets are the original design water jets for the Mark II PBR. The test craft was modified by installing new Detroit Diesel 6V53T series 7301 engines rated a 275-shp at 2,800 rpm. The standard engine for the PBR is the 6V53N series 7300 with a rating of 210-shp at 2,800 rpm. The purpose of the new engine is to improve the performance of the PBR by extending the combat load and at the same time extending the rpm operating range that the craft can sustain a planing condi- tion. The first jet tested was the Nomera 14, and the craft was able to achieve 31.3 knots at 2,892 rpm and 30.2 knots at 2,779 rpm in the light load condition. For the full load displacement, the Nomera jet pro- duced a maximum speed of 30.2 knots. In the full load condition, the rpm-range of operation capable of sustaining a planing condition of the craft with the Nomera jet was 2,660 to 2,889 rpm, 2,500 rpm in the light condition. Also, in full load conditions, the time to reach plan- ing speed for the Nomera jets was 60 seconds. According to North America Marine Jets, all performance results for the Nomera 14 water jet were better than the competing model's results.
