Model: E181S

This is a NEW 3.0L complete sterndrive package.  This 3.0L complete sterndrive package is ideal for replacing most  Mercruiser, Marine Power and OMC 3.0L marine engines.

Our complete engines are ideal for full repower of the weekend cruiser or family ski boat.  Our complete engines are manufactured by Marine Power and held to the same quality standards as their OEM (original equipment manufacturer) products.  The complete engine leaves you with the peace of mind of all new parts when cruising the water.  Although hard to exactly match every prior engine application, our Marine Power complete engines are designed and engineered to match other manufacturer’s applications closely to reduce labor and modifications during installation.  Our complete engines have options choices to match or upgrade from your current engine.
