MerCruiser 4 cylinder engine parts

Background and history of 4 cylinder engines

The most commonly used engines for American speedboats are the MerCruiser 120hp 4 cylinder 2.5 liter (151 cid) and the 140hp 3.0 liter (181 cid) variants. The 120hp 4 cylinder MerCruiser engine is an old engine and was primarily used from 1964 to 1989. The 140hp 4 cylinderMerCruiser engine is the successor and has been used since 1968 to the present. Another widely used engine is that of General Motors (GM). The basis of the GM has been used in the Pontiac, among others.

Characteristics of the 4 cylinder

In addition to the 4 cylinder 2.5 liter 120hp and the 3.0 liter 140hp engine, MerCruiser itself designed and marketed the 4 cylinder 3.7 liter (224 cid) engine. These engines were built between 1976 and 1989. In this range, 165hp, 170hp, 180hp, 185hp, and 190hp versions were delivered. Fortunately, many parts of the 4 cylinder engines are interchangeable with the 2.5 and 3.0 liter engines. The distributor cap, rotor, contact points, condenser, fuel pump, water circulation pump, and several other items are the same. For annual maintenance for this engine, you should at least think about renewing the gasoline filter and the oil filter. In addition, it is wise to change the engine oil.
