MerCruiser 4 Cylinder Sterndrive Engines | 3.0L & 470 Models

MerCruiser 4 cylinder engines date back to the 1965 model Renault engines, and the 3.7L 470 sterndrive and inboard models in the mid 1980's which Mercury Marine die cast the engine block in-house at the Stillwater OK location. The 4 cylinders engine models are still being produced today with the current 3.0L 181 Cu-In sterndrive model. PPT's interactive OEM Marine Parts catalogs allow easy lookup and searching for a range of engine models. MerCruiser has produced several different versions of the current 3.0L Engine Model however many customers mistakenly confuse the 2.5L 4 Cylinder Engine Model engine with the more current 3.0L 4 Cylinder Engine Models. Once the 2.5L engine model was discontinued MerCruiser did in fact offer several versions of the 3.0L engine; one the however being the 3.0L "L" Series Engine Models and the other being the 3.0L "LX" Series Engine Models. The 3.0L "L" Model engines utilized a cylinder head with larger ports whereas the 3.0L "LX" models utilized a smaller rectangular port cylinder head. In approximately 1995-1996 time frame the MerCruiser 3.0L "L" model was discontinued for the 3.0L "LX" model and became the only 4 Cylinder Sterndrive Engine option offered by MerCruiser going forward. At this time MerCruiser redesigned the exhaust manifold and eliminated the one piece manifold with cast end caps and replaced it with a single manifold design p/n 806867 that was produced in two different version to be used on the 3.0L "LX" Engine Models going forward as well as replacing the older 3.0L "L" Engine Models for field service replacement purposes. Today the OEM MerCruiser P/N 806867 Exhaust Manifold Series have been replaced with the current OEM Lost Foam Casting P/N 860235 Series 3.0L Exhaust Manifolds.
