Auto PSRU's

The most advanced PSRU’s available.

Advantages

  1. Centrifugal Clutch
    1. Engages & disengages at 800 to 900 RPM
    2. Eliminates high starter loads and burnout
    3. Eliminates propeller kick-back & damaging harmonics
    4. Makes the engine think it’s still in a car
    5. Clutch stays engaged so propeller can be used as a speed brake.
  2. Straight Cut Gears
    1. Most efficient transfer of power
    2. Eliminates fwd/aft thrust loads into drive shafts and into front and rear of case reducing weight
    3. Light weight heat treated gears for maximum strength and crown shaved for quiet operation
  3. Separate Lubrication System
    1. Allows the use of proper gear lubricants
    2. All bearings (100% roller) are pressure lubricated
    3. Eliminates extra heat load on engine oil
    4. Supports Hydraulic constant speed propellers
  4. LS3 More Power – less costs & weight
    1. Firewall Forward packages less than $40K versus certified engines at $112K+
    2. Everything between the firewall and propeller; 604 lbs for IO-540-K vs 580 lbs for LS3 (24lbs less)
    3. 300HP/575lb-ft for IO-540-K versus 365HP/700lb-ft at the propeller for LS3 (22% more)
    4. Fuel burn is 30% less per hour, plus cruise and maintenance costs are 90% less
  5. Automated Engine Controls
    1. Automatic computer controlled timing and mixture to over 14,700 ft. with a stock ECU
