A 7″ touchscreen is offset to give the driver unobstructed views and offers one-touch toggling between home, control, AutoWake® and Navigation display views.



There is no need to upgrade to a close-cooled engine with Moomba. Every Raptor by Indmar engine is close-cooled as factory equipment. Even on the base Raptor 400. Boom.


The 6.2L Raptor Series is inherently more efficient, giving you more low-end power while consuming less fuel. That conveniently translates to more time on the water and less time at the pump.
