OJ 3018 EVO Series 16.5 x 14.75 LH Propeller, Replaces OJ 1847

OJ EVO 3018 Propeller Specifications

The OJ EVO 3018 propeller is a four-blade, 16.5 x 14.75 left-hand inboard propeller designed for compatible wakeboard and wakesurf boats. Part of the OJ Evolution series from Johnson Propeller Company, the EVO 3018 combines a redesigned blade shape with revised pitch distribution developed to improve surf performance and efficiency.

Featuring a splined bore and .140-inch cup, the OJ 3018 is the listed replacement for the OJ 1847 propeller. Whether replacing your existing propeller, purchasing a matching spare or evaluating a different setup, choosing the appropriate model starts with your boat’s propulsion system and operating requirements.

OJ Evolution Design for Surf Performance

The Evolution series builds on OJ’s established WAKEPRO and V-4 designs with updates to blade geometry and the distribution of pitch across the blades. These refinements focus on improving surf performance and efficiency for compatible inboard applications.

The EVO 3018 brings those design changes to a 16.5-inch diameter and 14.75-inch pitch configuration. Actual performance depends on your engine, transmission ratio, hull design and operating load, including ballast, passengers and equipment.

OJ 1847 Replacement Propeller

If your existing propeller is stamped OJ 1847, the OJ EVO 3018 is a listed Evolution series replacement. It incorporates the newer series’ blade design and pitch distribution while providing an option for compatible splined-shaft applications.

When replacing an older propeller, compare the complete configuration and account for any previous pitch or cup modifications. A propeller that has been customized may perform differently from an unmodified replacement.

Choosing the Right Propeller for Your Boat

Wakeboard and wakesurf boats carry different combinations of ballast, passengers and gear. Consider your typical load, intended use and the engine manufacturer’s recommended operating RPM range when selecting an inboard propeller.

The EVO 3018 requires a compatible splined shaft, left-hand rotation and sufficient hull clearance for its 16.5-inch diameter. For boats currently using another propeller model, matching diameter and pitch alone does not establish compatibility.

A matching OJ EVO 3018 spare can also help reduce downtime following unexpected propeller damage and keep a suitable replacement available for future boating trips.
