Mercury 8M0238904 Fury 4 14.5 x 23P Propeller

The Mercury 8M0238904 Fury 4 14.5 x 23P Propeller is a high-performance four-blade propeller engineered for demanding bass boat and tournament applications. Featuring a 14.5-inch diameter, 23-inch pitch, and standard right-hand rotation, the Fury 4 is designed to deliver strong acceleration, additional lift, excellent handling, and reliable grip when operating with heavier boat loads.

Built using Mercury X7 alloy, the Fury 4 combines strength and durability with precision-engineered blade geometry. Mercury states that its X7 alloy is 30% stronger and four times more durable than conventional stainless steel. The four-blade design provides the additional lift and holding performance needed for boats carrying substantial amounts of fuel, batteries, tackle, livewell water, and other tournament equipment.

Performance and Design

The Mercury Fury 4 14.5 x 23P propeller is designed to provide a balanced combination of speed, acceleration, and handling. Its four-blade configuration helps maintain grip and control in rough-water conditions while providing strong midrange acceleration.

The propeller incorporates Mercury’s Performance Vent System (PVS), with two PVS holes per blade. The interchangeable vent plugs allow the propeller’s ventilation characteristics to be adjusted to suit the boat and application, helping optimize hole shot, engine RPM, and acceleration.

For heavily loaded tournament boats, the Fury 4 can provide additional lift compared with a three-blade Fury of the same pitch. This makes it particularly well suited to anglers and boat owners who regularly operate with heavier loads and want responsive acceleration and dependable handling.
