Common Concerns Answered
Is a hub kit included with this propeller?
No, a specific hub kit is required for installation and must be purchased separately, selected based on your engine model.
Will I lose top-end speed compared to a 3-blade propeller?
While some users may observe a marginal reduction in top-end speed depending on the specific boat and engine configuration, the performance gains in hole shot, handling, and stability generally outweigh this factor for most applications.
How does customer sentiment reflect the performance of this propeller?
Customer feedback is overwhelmingly positive, with users consistently reporting significant improvements in hole shot, handling, and overall vessel stability, frequently citing it as a substantial upgrade over their original equipment propellers.
Frequently Asked Questions
What is the primary benefit of the Turning Point Express Mach4 propeller?
The primary benefit is its unique combination of exceptional hole shot, superior handling, enhanced rough water stability, and significantly increased reverse thrust, all without compromising top-end speed.
What type of boats is the Turning Point Express Mach4 propeller best suited for?
It is best suited for sterndrive boats, tri-toons, bay boats, and any vessel that can benefit from increased stern lift and improved acceleration, particularly those with 40-150hp engines.
What is TP17 stainless steel and why is it important for this propeller?
TP17 stainless steel is an advanced alloy with 20% higher chromium content than standard stainless steel, providing superior corrosion resistance and nearly 250% greater strength and durability, ensuring longevity and performance in harsh marine environments.
How does the exhaust port design of this propeller improve performance?
The large, free-flowing exhaust ports facilitate efficient exhaust gas scavenging, allowing the engine to breathe better and produce maximum horsepower, contributing to improved overall performance and acceleration.
Is a hub kit required for installation of the Turning Point Express Mach4 propeller?
Yes, a dedicated Turning Point hub kit is mandatory for the installation of this propeller. The correct hub kit must be selected based on the specific engine model for proper fitment and function.
