Types of MerCruiser Diesel Engines for Sale

MerCruiser diesel engines for sale are two kinds of engine systems: inboard and sterndrive. The inboard engine is installed in the boat hull. It is connected to the propeller via a drive shaft. The sterndrive engine system combines the inboard engine and transmission unit and is located outside the boat hull, usually at the rear. Both the inboard and sterndrive engine systems are generally installed in the middle of a boat, and they provide powerful thrust and control.

Another popular MerCruiser engine system is the outboard engine system. MerCruiser does not manufacture the outboard engines, but some boats will carry a MerCruiser engine with an outboard engine made by another manufacturer. This engine system is usually fixed on the transom, i.e. the rear side of the boat.

The two MerCruiser diesel engine series are as follows:

• 611 Z Entry Series:

  The MerCruiser 611 Z diesel Z drive engine has an output of 675 hp at 2500 rpm. Its transmission rating is 8135 Nm.

With a block and head material made of cast iron, there is flexible coupling for all propeller shafts. The 611 Z has a V6 configuration with a 95-degree angle between the cylinder banks. The maximum torque is 798 Nm. In some boats, the 611 Z diesel drive unit may be combined with a 675 hp MerCruiser gasoline engine for sterndrive propulsion in the crossing of hybrid propulsion systems.

• Duarable Series:

  The MerCruiser Diesel Duramax engine has an output of 300 hp. Its transmission rating is 440Nm. The maximum torque of MerCruiser 4500-5126 engines is 760 Nm.
