OJ 1284 Force 14" x 18" 4 Blade Propeller

OJ 1284 REPLACMENT PART OJ 450

The OJ 1284 Force 4-Blade Propeller is an original OJ inboard boat propeller designed to provide strong pulling power and smooth, consistent performance. The OJ Force series was developed for tournament towboats and recreational ski boat applications.

If you are searching for an OJ 1284 propeller, an OJ 1284 replacement, or a 14 x 18 right-hand inboard propeller with a 1-1/8-inch shaft connection, Prop Depot can help you identify the correct propeller for your boat.

Looking for an OJ 1284 Replacement Propeller?

If your original OJ 1284 propeller is damaged, worn, or no longer available, finding the correct replacement requires matching the original propeller specifications and confirming compatibility with your boat and drivetrain.

The OJ 1284 is the right-hand version of the OJ 1281, which has a separately listed machined replacement. However, the replacement part number for the OJ 1284 should be confirmed independently because rotation is critical to proper fitment.

Prop Depot can help identify an appropriate machined OJ replacement or another compatible inboard propeller for your application.

Confirm Propeller Fitment

Before ordering an OJ 1284 replacement propeller, verify:

• Boat make, model, and year
• Engine manufacturer and horsepower
• Transmission gear ratio
• Original propeller diameter and pitch
• Blade count and rotation
• Shaft diameter and connection
• Intended boating use

Contact Prop Depot for assistance confirming the correct replacement propeller.
