New 7.4L GM Marine Partial Engine Package
Model: 882740 This is a brand NEW General Motors marine base engine.  This 7.4L Marine engine is built strictly for marine use on GM production lines.

Our Parpacs were created and built by Marine Power.  Parpacs are held to the same quality standards as Marine Power’s complete engines.  Parpacs are ideal for numerous replacement situations.  Parpacs are the perfect solution for replacing Pre-Vortec engines. The Parpac solves the problem of the intake manifold bolt pattern by providing a new installed intake manifold and carburetor. The Parpac also includes the installed electronic fuel pump as opposed to the Pre-Vortec mechanical fuel pump.
