The OJ 1239 Force 4-Blade Propeller is designed to deliver strong, smooth, and consistent pulling performance for inboard-powered ski boats and wakeboard boats. The OJ Force series was the first four-blade propeller design introduced by OJ to provide tournament tow boats with an exceptionally smooth and steady pull.
If you are searching for an OJ 1239 propeller, OJ Force 13 x 14 propeller, or OJ 1239 replacement, this handcrafted NiBrAl propeller features right-hand rotation, a 1-inch shaft bore, and .090-inch cup.
OJ 1239 Propeller Applications
The OJ 1239 Force propeller is designed for Correct Craft and other right-hand rotation inboard boats equipped with a 454 or high-torque 351 engine.
The 13 x 14 four-blade configuration is designed to reduce engine RPM approximately 150–200 RPM compared with a 13 x 13 propeller, depending on the boat and drivetrain setup.
Looking for an OJ 1239 Replacement Propeller?
If your original OJ 1239 propeller is damaged or you need a replacement, Prop Depot can help identify the appropriate current OJ propeller for your application.
When selecting a replacement, it is important to match the original diameter, pitch, blade count, rotation, and shaft connection. A similar-looking propeller is not necessarily a direct replacement.
Confirm Propeller Fitment
Before ordering an OJ 1239 replacement propeller, verify:
- Boat make, model, and year
- Engine manufacturer and horsepower
- Transmission gear ratio
- Original propeller diameter and pitch
- Rotation and shaft bore
- Intended boating use and performance requirements
Contact Prop Depot for assistance confirming the correct replacement propeller for your boat.
