Specifications
The Turning Point Propellers 31502321 Express 3 Blade SS Propellers For 90 300+Hp Engines With 4.75in Gc 14.25in x 23in LH Ex 1423 L boasts a 14.25-inch diameter and a 23-inch pitch, designed to optimize performance for engines ranging from 90 to over 300 horsepower. This particular propeller is a left-hand rotation model, crucial for twin-engine setups where opposite rotation is required for counteracting torque. Its construction is 3-blade stainless steel, offering superior strength and durability compared to aluminum alternatives. The 4.75-inch gearcase compatibility ensures it will fit a wide array of modern outboard and sterndrive lower units. This propeller’s specific design aims to enhance a boat’s speed and handling characteristics, making it a significant upgrade from standard aluminum propellers, particularly in its ability to withstand higher loads and generate more thrust.
Performance & Functionality
In terms of core function, the Turning Point Propellers 31502321 Express 3 Blade SS Propellers For 90 300+Hp Engines With 4.75in Gc 14.25in x 23in LH Ex 1423 L excels at delivering powerful acceleration and impressive top-end speed. Its aggressive pitch angles and radical design, as described by Turning Point Propellers, translate directly into a more responsive feel right off the line. The propeller cuts through the water cleanly, minimizing ventilation and blow-out even during sharp turns or aggressive acceleration. One of its strongest points is its ability to maintain planing speed at lower engine RPMs, contributing to better fuel economy on longer runs. The only minor area where it might not be the absolute best is in extremely slow-speed maneuvering in tight quarters, where a propeller with a different pitch or blade count might offer slightly more control, but this is a trade-off for its high-performance capabilities.
Design & Ergonomics
The design of this Turning Point Propeller is clearly geared towards performance. The aggressive pitch angles and sharp cup profiles are not just for show; they are engineered to maximize hydrodynamic efficiency and grip the water effectively. The stainless steel construction provides a reassuring heft and a smooth, polished finish that resists fouling and damage. While the propeller itself isn’t “ergonomic” in the traditional sense of something held in hand, its performance translates into a more comfortable and less fatiguing boating experience. The smooth operation and reduced engine strain mean less vibration transmitted to the boat and its occupants. The markings, such as the propeller number EX-1423-L, are clearly stamped, aiding in identification and reordering.
Durability & Maintenance
