Introducing the Marine Power LT4 AirPac engine. A 620 Horsepower Supercharged Direct Injected engine designed and calibrated specifically for Airboat applications.

The New 6.2L LT4 AirPac Engine features the latest technology from both Marine Power and General Motors. We start off with a new marine Industrial base engine that features state of the art direct fuel injection. Controlled by a MEFI 7 ECM the Direct Injection allows the engine to make more horsepower while burning less fuel and achieving greater combustion efficiency than engines with conventional port injection. That along with the Marine Power self contained high pressure fuel system and other industry leading products makes this fresh water cooled engine the perfect option for a new boat build or your repower needs.
