The OJ 1784 WakePro V4 is a high-performance 4-blade propeller designed for wake and surf boats that need strong low-end power and smooth acceleration. With an 18" diameter and 14" pitch, it delivers an excellent hole shot and improved pulling power, making it ideal for boats running ballast or towing riders. Built from durable CNC-machined NiBrAl (Nickel-Bronze-Aluminum) and featuring .120 cup technology, it provides a strong grip in the water, reduced cavitation, and efficient performance. The 1-1/4" bore, left-hand rotation design fits many inboard tow boats and helps maintain consistent RPMs while delivering reliable torque and smooth operation.
