 ULTRAJET 305 FOR 31′ BOWPICKERA single UltraJet 305 propels this aluminum bowpicker operating in Cordova, Alaska. Owner Jeff Phillips replaced the originally installed jet with the UltraJet matched to the existing Volvo 63L engine. Jeff states, “I am … able to run 100-200 rpm’s lower with the Ultra Jet than I did with the Hamilton (jet), and my speed is better than before, even at those lower rpm’s. It will definitely push more weight, although I haven’t determined what it won’t push. I have been able to plane with 800-1000 pounds of fish onboard in the ocean… . With the Hamilton, I virtually was done planing with half of that weight.” MP7932 |

 WORKBOAT ACHIEVES NEAR 40 KNOTSThis 45′ workboat is propelled by twin UltraJet 340 units each powered by a 430 hp Cummins 6CTA8.3M diesel engine via ZF305 transmission. Other than that, we let the boat owner/operator speak for the UltraJet units: “We were very impressed by the performance of our new boat; it’s very responsive and jumps onto plane in no time. The maneuverability that the jets provide us with is exceptional and the load carrying capabilities and speeds we are achieving are also impressive. With one quarter of fuel and a crew of two we are getting close to 40 knots top speed! This is better than we had ever hoped for. On one occasion we added an extra 8 tons of load to the boat and were still able to get 28 knots! That was really impressive! In another we towed a boat that weighed 100 tons at a speed of 12 knots.” ME6417 Click here to request a PDF with more information. |
