Australia's Largest Supplier of Turn Key Performance Marine Engines.

Performance Marine Engine | 355ci Chevrolet Marine V8

Re-power your ski boat with a correctly built Marine engine. 'Not a passenger car crate engine.

Why a Custom Built Marine Engine?

A number of reasons:

  • If your boat is used in salt water it requires special gaskets to prevent corrosion to your engine.
  • Aluminium manifolds and other aluminium parts cannot be used as they very quickly corrode.
  • Generally a ski boat operates under high load on every outing. Not like your car.
  • Torque requirements are completely
    different.
  • Our purpose built marine engines make
    torque at low RPM where its needed.
    Only the correct camshaft and cylinder
    head combination will acheive this.

Our most popular Performance Marine Engine is the 355 Cubic inch Chevrolet.
