Frequently Asked Questions (FAQs)

Q: Does this propeller include the inner hub kit?A: No. Turning Point propellers utilize an interchangeable MasterTorque Hub Kit system (sold separately). You will need to select the matching 400 or 500 series hub kit for your specific outboard or sterndrive brand and horsepower.

Q: What type of boating benefits most from a 4-blade 23-pitch propeller?A: A 4-blade 23-pitch prop is ideal for high-performance bowriders, bay boats, and runabouts with higher horsepower engines that need strong hole-shot acceleration for watersports, quick planing under heavy passenger loads, and superior handling in choppy waters.

Q: How does Turning Point's stainless steel material compare to standard stainless props?A: Turning Point uses a proprietary stainless steel formulation with 20% higher chromium content. This yields a brighter polish, significantly higher corrosion resistance, and almost 250% greater material strength, allowing thinner, more efficient blade designs without blade flexing.

Important: A compatible Turning Point hub installation kit is required and sold separately. Select the correct hub kit based on your engine manufacturer, model, and gearcase.

Propeller Selection & Compatibility

Proper propeller selection depends on engine horsepower, gearcase dimensions, boat weight, operating conditions, and recommended wide-open-throttle RPM range.

Before ordering, verify that the 14" x 23" right-hand propeller is appropriate for your application using the Turning Point Prop Wizard or manufacturer selection chart.

Installation Note: Follow the engine manufacturer's propeller installation procedures and torque specifications. Confirm hub kit compatibility before installation.
