New 6.0L Inboard/Outboard Replacement Engine.
 
This engine is equipped with GM's MEFI 6 controller and custom Marine Power calibration.
The engine has closed cooling, fuel injection, top mounted high torque marine starter and aluminum performance exhaust manifolds.
 
Note: Picture is shown with catalyst exhaust system ($1100 premium & not included).
 
Catalyst exhaust is only needed when original engine in the vessel had a catalyst system.
Most re-powers will not need the catalyst system.
