New 7.4L GM Marine Long Block
Model: 881740 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 GM Marine long blocks are ideal for replacing an engine when the component parts are still good.  Why replace it if it is not broken?  However, we do recommend replacing warn out components.  All engines, unless clearly stated, are authentic General Motors Marine engines.  Our authentic GM marine engines are built on GM production lines for marine applications.  Don't be mislead by others who can't claim GM authenticity unless you are satisfied with an imitation.
