Nizpro SHO 4.2L V6 Lower Unit High Performance Nosecone 2025 DIY Kit

Nizpro Marine constantly innovates, pushing the boundaries of performance for your Yamaha V6 4.2L outboard engine and boat setup.

While nose cone extensions aren’t new, their impact on performance is significant, and for 2025, Nizpro have taken it a step further.

The Nizpro engineering team has completely redesigned the SHO 4.2L V6 High Performance Lower Unit Nose Cone which is now now available to easily self install in a DIY Kit,  focused on an easy-to-install solution that anyone can follow, thanks to clear, step-by-step photo instructions.

For this 2025 release, Nizpro set four key design objectives:

• Eliminate welding during installation.

• Reduce hydrodynamic drag for improved performance.

• Enhance engine water supply at high running positions with dual inlets under cone.

• Improve steering accuracy and responsiveness.

By harnessing cutting-edge 3D scanning, CAD (Computer-Aided Design), and CFD (Computational Fluid Dynamics) technologies, Nizpro have met and surpassed each of these goals.
