Tested and Proven. Efficient and Powerful.
For over 40 years, the future of competition-bred inboard engines has been written, and re-written, by Indmar. The lessons we learn as the official power of the most demanding competitive water sports events translate directly to the Indmar engines we have built for every top inboard boat builder around the world. Lessons rooted in the principle of maximizing performance without compromising efficiency.
In other words, Indmar Intelligent Performance. The exclusive 3G ECM is custom calibrated with towboat specific software that delivers seamless integration to monitor and adjust the air/fuel mixture while utilizing Indmar’s ETX/CAT to minimize emissions. On the lake, Indmar’s engine performance is almost rocket like while maximizing fuel efficiency.
