MONSOON Engines

Thanks to a close partnership with GM Marine and following the strictest industry standards, Monsoon engines are produced in a state-of-the-art engine facility in Tennessee. Technology is the key behind our new ultra-clean engines. It all starts with direct injection, which bypasses the air intake manifold and injects fuel directly into the combustion chamber, making for a cleaner, more controlled and complete burn resulting in improved fuel economy.

Award-Winning Performance, Unmatched Reliability

The Monsoon line of engines, the 5.3L, and 6.2L, were developed to offer unmatched performance, fuel economy, reliability and sound reduction. The 6.2L even has the lowest sound level at various RPM’s and fuel economy levels comparable to smaller engines. Working with industry leaders like GM ® Marine, Roush ® , Davinci ® , and McLaren Engineering ® to design and perform the research and development necessary to introduce a line of direct injection engines to the boating industry like no other.
