Marinization of GM Engine

Malibu Boats

Malibu Boats is the world’s largest manufacturer of performance water sports boats with a focus on state-of-the-art innovation. With innovation as their driving force, Malibu has brought many firsts to the towboat industry: the first Wakeboard Hull, the Wedge Hydrofoil, the Power Wedge, and Surf Gate™ – a way to create endless, fully customizable surf waves.

We were approached by Malibu to help execute the marinization of a GM engine for their water sports boats. Our team of engineers worked alongside theirs to deliver the industry’s most reliable, economical, and quietest engine. We designed the marinization, created prototypes, and helped source the best suppliers. We executed CAD modeling, CFD analysis of the engine manifolds, drawings, and industrial design of the top end engine. We tackled various components of engine marinization from water-cooled exhaust manifolds to front end dress adaptation, and we developed a custom exhaust system that is CARB 5-star rated as the lowest emitting engine on the market. This project is currently confidential, but we are honored to continue to work with Malibu to provide the best-in-class products to their customers.

What is extremely important to any project, is the people that you have leading, developing and executing it, which is why working with Davinci has been such a crucial relationship in the marinization of our engine. Davinci has been a key part in helping to develop a cooling system to minimize all risk while you’re enjoying a day out on the water.
