Hustler Aluminum Boat Propellers
Stainless Steel Performance at Aluminum Prices
Stainless steel blade geometry used in aluminum propellers results in superior performance. Higher efficiency equals better fuel economy, better top end, faster hole shot, and excellent cornering and handling.
Tuned Vents for Fast Hole Shot
Vent holes in the propeller's barrel allow exhaust gases to escape, reducing water density around the propeller's blades during acceleration. This causes the propeller to rotate faster at slower speeds resulting in more horsepower. More horsepower at lower speeds means faster acceleration and a faster hole shot. Turning Point is the only manufacturer offering this race proven feature in our Hustler aluminum propellers on most models (selected models only 13" & 14" diameter 17+ Pitch).
Squeeze Cast for Added Strength
Turning Point's squeeze cast process generates the highest mechanical properties attainable in a cast product, resulting in tighter grain structures. Competitors use old Die Cast processes that results in a high blade flex and poor performance.
Performance Tuned Rake Angles
Higher rake angles tighten the vortex produced by the propellers, adding to boat lift and overall performance.
Improve Handling and Boat Lift
Through aggressive rake and cupping.
High Flow-Through Barrel Exhaust System
Maximizing exhaust flow increases horsepower and top end speed.
Tuned Progressive Pitch Angles
Accelerating and channeling water to minimize slip increases performance and fuel economy.
Long Lasting Powder Coated Finish
Turning Point's 5 step process creates a uniform, durable, high quality, and attractive finish that protects the aluminum from corrosion.
