MODEL SD-309

ADVANTAGES TO USING AMERICAN TURBINE'S NEW SUPER DUTY JET

  • Engine and jet sit four inches farther back for more interior room. 
  • Bearing housing held on with six bolts instead of four to better support the rear of the engine. 
  • Completely sealed bearing housing water can't come in around the driveshaft. 
  • A larger thrust bearing 35% more load capacity 
  • Mechanical pumpshaft seal, never needs adjusting. 
  • Stronger 416 stainless steel pumpshaft. 
  • Shouldered wear ring prevents cavitation. 
  • Heat-treated aluminum impeller standard. 
  • Secondary wear ring on the rear of the impeller to prevent bowl cavitation. 
  • Jet will accept the new 9.5" impeller. 
  • Tandem lip seals on the bowl bearings, keeps grease in grit out. 
  • Fifth generation bowl, better flow than any other mixed flow pump. 
  • High flow nozzle assembly with pressure sealed TFE o-ring that does not leak after a few hours. 
  • Nozzle inserts to fine tune your boat for optimum take-off and top speed or part throttle fuel economy, i.e. smaller nozzle, higher pressure, better take-off and top speed, larger nozzle better cruise. 
  • HTR reverse bucket, sand lock resistant, self-closing design, much easier on cable and shifter. 
  • Highest static reverse of any mixed flow pump. 
  • Tiller arm bolted on in two places for added safety. 
  • Transom flange cast into suction housing, no need to make plates. 
  • Transom flange bolts to transom so the integrity of the transom is increased. 
  • Water off-takes are piped through the transom flange with a hose barb requiring less rigging time. 
  • Ball and socket type steering kit, easier and quicker to center steering wheel and much nicer looking than two nuts and a piece of rubber hose. 
  • Hand hole cover outside of transom for easier access. 
  • Intake flange twice as thick for added strength. 
  • Power and manual trims available. Light weight, 99 pounds (jet unit).
