OJ 1778 WakePro V4 Propeller – Replaced by OJ EVO 3767

The OJ 1778 WakePro V4 4-blade propeller has been replaced by the OJ EVO 3767 Evolution Series propeller. If you are searching for an OJ 1778 propeller, an OJ 1778 replacement, or a replacement inboard propeller for your wakeboard or wakesurf boat, the OJ EVO 3767 is the updated model to consider.

The original OJ 1778 WakePro V4 measures 17 inches in diameter with a 15.5-inch pitch. It features four blades, left-hand rotation, a 1-1/4-inch shaft bore, and .120 cup. The WakePro V4 design features a refined blade shape and pitch distribution intended to balance low-end pulling power with top-end performance.

OJ 1778 Replacement: OJ EVO 3767

The OJ EVO 3767 is the updated replacement for the discontinued OJ 1778 WakePro V4. The OJ Evolution Series features a redesigned blade shape and optimized pitch distribution, developed to improve surf performance and efficiency.

If your existing propeller is stamped OJ 1778, the OJ EVO 3767 is the replacement model to consider. Since the EVO design differs from the original WakePro V4, confirm compatibility with your boat, engine, shaft configuration, and performance requirements before ordering.
