The heart of the Airmaxx is a current production GM 6.6L L5P Duramax engine. Marine Power chose this platform because of it's proven performance with reliability. This is the first marinized Duramax that has GM support, and utilizes a GM engine controller. This package is so unique it created a segment in the market nobody knew existed. The Airmaxx package includes a 7" Medallion Instruments display, main engine harness, GM foot throttle, K&N air filter, and fuel lift pump.

State of the Art Technologies

Electronically Controlled, Variable-Geometry Turbocharger

• Variable vane mechanism allows greater exhaust temperature capability, enabling the engine to achieve higher power at lower cylinder pressure.

Cold-Start System

• Fuel injection system and combustion chamber shape helps optimize cold weather performance
• Enhanced ceramic glow plugs and automatic temperature compensation assist with quicker heat ups and reliable starting down to -40 deg.

Robust Crank and Valvetrain Designs

• Updated crankshaft with induction hardened main bearing journals and high pressure rolled fillets for strength and longevity.
• Pistons with refined aluminum material along with an oil cooling gallery help maximize performance and robustness vs previous Duramax® 6.6L engines.
