The LT4 Marine 6.2L DI is one of our go-to powerplants when the job calls for strong torque, clean throttle response, and reliable power under load. It’s built on proven GM architecture and designed for marine use—meaning it’s meant to work, not just look good on a spec sheet.
The Levitator LSX MS 70 is 7.4 liters of naturally aspirated muscle built for airboat duty—simple, strong, and made to pull. It’s based on proven LSX architecture and delivers the kind of torque that matters when you’re moving real weight, running rough terrain, or spending long days on the throttle.
If you’re after diesel torque and long-haul reliability, the 6.6L Duramax L5P package is built for that kind of work. Marine Power starts with the current-production GM Duramax L5P as the base and marinizes it into a clean, efficient, low-vibration diesel that’s meant to run steady under load.
The 6.2L AirPac is Marine Power’s airboat-specific small-block package, built around a 6.2L platform and designed for the fast throttle changes and constant load shifts airboats see. Depending on configuration, Marine Power offers AirPac setups that include direct-injection Gen V options (MEFI 7 controlled) and supercharged AirPac variants.
Got a different engine in mind? If it’s rated for airboat use, we can install it—no matter the manufacturer. As long as it can be shipped to Patriot, we’ll set it up, install it, and make sure it’s dialed in for your build.
