OJ 1921 WakePro V4 15" x 13.5" Propeller

OJ 1921 WakePro V4 Propeller – Discontinued and Replaced by OJ EVO 3922

The OJ 1921 WakePro V4 4-blade propeller has been discontinued and replaced by the OJ EVO 3922-MF Evolution Series propeller. If you are searching for an OJ 1921 propeller, an OJ 1921 replacement, or a replacement inboard propeller for your wakeboard or wakesurf boat, the OJ EVO 3922-MF is the updated model to consider.

The original OJ 1921 WakePro V4 measures 15 inches in diameter with a 13.5-inch pitch. It features four blades, left-hand rotation, a 1-1/8-inch shaft bore, and .120-inch cup. The WakePro V4 design was developed to balance low-end pulling power with top-end performance for inboard towboats.

OJ 1921 Replacement: OJ EVO 3922-MF

The OJ EVO 3922-MF is the updated replacement for the discontinued OJ 1921 WakePro V4. The OJ Evolution Series features a redesigned blade shape and optimized pitch distribution intended to improve surf performance and efficiency.

If your existing propeller is stamped OJ 1921, the OJ EVO 3922-MF 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.
