Boating Benefits

  • The MEFI 3 Electronic Control Module, which provides precise fuel and spark control and unmatched top-end throttle response.
  • Heavy-duty GM® performance parts including forged crankshaft, connecting rods and pistons.
  • A thermostatically controlled, high-capacity oil cooler to bring engine oil temperatures up quickly and keep them more consistent.
  • Oil thermostat and a Positive Crankcase Ventilation (PCV) valve that work together to reduce the buildup of condensation in the oil. The PCV valve also improves engine idle.
