A recent post focused on sterndrives, and Mercruiser by Mercury Marine is the most popular one available in America. Mercruiser exposes engine systems to rigorous testing in the toughest conditions to assist in the development of some of the strongest and most reliable sterndrive packages in the industry. They cast components in special alloys and utilize computer-controlled painting processes that have withstood immersion and corrosion testing. Mercruisers also include an expanded passageway in the exhaust elbow to prevent saltwater from clogging the system. The standard production gas sterndrive and inboard packages by Mercruiser are protected by Mercury Marine’s three-year limited warranty against corrosion failure. Check your operation and maintenance manual for complete information regarding warranty.
Power steering is standard on all Mercruiser sterndrives 4.3L and larger and are optional on the 3.0L. 3- and 6-inch risers to further prevent saltwater clogging are optional on all Mercruiser sterndrives and inboards with the exception of the 3.0L. Remote oil filters are standard on all gas fuel-injected sterndrives, Bluewater inboards, diesel engines, and are available as a kit for all carburetor sterndrive models. There is an audio warning system mounted under the helm to alert the boater to low Mercury engine oil pressure, high engine temperature, and other potentially damaging engine conditions which is standard on all gas and diesel models, available as a kit on the 3.0L sterndrives.
