Common Concerns Answered
Will I need to purchase additional components for installation?
Yes, this propeller requires the purchase of a Turning Point MasterGuard Installation Kit separately. Ensure you select the correct kit compatible with your specific engine model.
Will this propeller reduce my top-end speed?
While some users may experience a marginal reduction in top-end speed compared to a 3-blade propeller, this is a common trade-off for the significant gains in hole shot, mid-range acceleration, and overall handling the Mach4 provides.
How does the TP17™ stainless steel compare to standard stainless steel?
TP17™ stainless steel offers superior strength and durability, featuring 20% higher chromium content, 250% greater strength, and 5 times the durability of standard stainless steel, ensuring a longer service life and resistance to corrosion.
Frequently Asked Questions
What is the primary benefit of the Turning Point Express Mach4 propeller?
The primary benefit is its unique combination of superior hole shot, enhanced handling, and rough water stability without sacrificing significant top-end speed, largely due to its advanced 4-blade Swept Cleaver design.
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 vessels used for watersports that require enhanced acceleration, improved handling, and increased load-carrying capacity.
What is TP17™ stainless steel?
TP17™ stainless steel is Turning Point's proprietary alloy, formulated with 20% higher chromium content, making it 250% stronger and 5 times more durable than standard stainless steel, providing exceptional corrosion resistance and structural integrity.
Does this propeller require a hub kit?
