NAP Series

Hung Shen NAP Series Propellers - Special Order

A Hung Shen NAP propeller is the right choice when smoothness, durability, and low cavitation matter more than outright top speed — making it ideal for commercial, passenger, and continuous-duty boats. Hung Shen NAP propellers feature a moderate-skew blade design that reduce noise, vibration, and cavitation, making them ideal for smooth, efficient inboard propulsion.
