Advantages

01

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.
02

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
03

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

Multiple gear ratios available

  1. Uses two gear sets available in 64 gear ratios making 150+ gear ratios from 1:1 through 3.54:1
  2. Multiple gear rations makes it very flexible for any engine between 150 to 300 HP
  3. The case is designed to be used with an adapter making it easy to mount on any engine.
  4. Designed with a vertical offset of 7.00 inches between the input shaft and propeller shaft. This makes it the perfect PSRU to inline 4 or 6 engines and V4, V6, or smaller V8 engines. Innovative features like these are why so many choose a 300Z PSRU Gearbox when matching to 150-300 HP engines.
