The Mercruiser 3.0L is a 135 horsepower, four-cylinder engine that often is found in small boat craft. A Mercruiser motor from 1988 requires regular tuning and servicing to keep the corresponding boat running properly.
Like automobile engines, the battery of a marine engine is vital to the starting and response of the engine during use. A slow starting engine is the sign of a battery that must be charged or replaced. If the boat has been sitting for a period of time without use, take the battery to your local dealer to charge. If the battery of the Mercruiser 3.0 has not been replaced in four or five years, then the battery should be removed and replaced with a newer, identical brand.
The 1988 Mercruiser 3.0L motor features a 2V Carb fuel system. Keeping the air and fuel mixture balanced properly is important, and changing the air filter regularly is one important step in this procedure.
Spark plugs and spark plug wires are some of the most inexpensive engine parts to replace, yet imperative to engine starting and consistent firing. Inspect spark plugs and corresponding wires for faults and physical damage, removing the necessary plugs and wires for replacement.
