OJ 3721 EVO Series 15 x 14.25 LH Propeller, Replaces OJ 748

The OJ EVO 3721 4-Blade Inboard Propeller is designed for compatible inboard wakeboard and wake-surf boats seeking improved surf performance and efficiency. Developed by Johnson Propeller as part of the OJ Props Evolution Series, the EVO 3721 features a redesigned blade shape and optimized pitch distribution evolved from OJ’s proven WAKEPRO and V-4 propeller designs.

With a 15-inch diameter, 14.25-inch pitch, and four-blade configuration, the OJ EVO 3721 is designed for compatible inboard applications requiring a standard 1.25-inch tapered propeller shaft. Its Evolution-series design focuses on improving surf performance and efficiency.

The OJ EVO 3721 replaces the OJ 748 propeller, making it a replacement option for boat owners upgrading from that earlier model. Confirm your boat’s shaft configuration and recommended propeller specifications before ordering.
