Performance-focused construction

• Four-blade design: Supports acceleration, handling, and stability in rough water.
• TP17 stainless steel: Turning Point's proprietary alloy is designed for strength, durability, and corrosion resistance.
• Swept-cleaver blade geometry: Intended to combine responsive handling with speed and stern lift.
• Free-flowing exhaust passages: Designed to promote exhaust flow and reduce backpressure.

Fit and installation

A matching hub kit is required for installation. Use the Turning Point Selection Chart or Prop Wizard to confirm the correct hub kit and propeller for your engine and boating requirements. Do not select fitment based on diameter and pitch alone.

The Express range serves a variety of outboard and sterndrive applications; compatibility varies by propeller and hub kit. Turning Point offers MasterGuard installation kits with a lifetime warranty. Confirm the applicable kit and warranty terms before ordering.
