🔧 Product Description

Genuine Turning Point Hustler Four-Blade Propeller with Mercury Hub - Part Number: 21431330 / 41510400

A genuine used Turning Point four-blade right-hand aluminium propeller supplied with a Mercury-pattern 15-spline hub.

The propeller housing is nominally 14 inches in diameter with 13 inches of pitch. Hub kit 41510400 configures the modular housing for compatible Mercury / Mariner V6 and MerCruiser large-gearcase applications.

⚙️ Key Features

• Genuine Turning Point Hustler four-blade propeller
• 14-inch diameter x 13-inch pitch
• Four-blade aluminium construction with right-hand rotation
• Includes or references Mercury 15-spline hub 41510400
• Designed for strong acceleration, stern lift and load carrying

🚤 Compatibility

Commonly used on

• Mercury / Mariner large 15-spline outboard gearcases
• MerCruiser Alpha One and Bravo One propeller systems where clearance and hub fitment are correct

Typically suits

• Engine models:
• Mercury / Mariner 135HP, 150HP, 175HP, 200HP, 225HP, 250HP and 300HP outboards
• Mercury Verado applications using the compatible 15-spline hub and 14-inch propeller clearance
• MerCruiser Alpha One and Bravo One sterndrives using the compatible 15-spline shaft
• Final suitability depends on hull load, drive ratio and the engine's full-throttle RPM range
• HP Range: 135HP - 300HP, plus compatible MerCruiser sterndrives
• Engine Type: Mercury / Mariner outboard or MerCruiser sterndrive with 15-spline shaft
• Year Range: Application controlled by gearcase, hub kit and propeller clearance

🔌 Function

The four-blade propeller provides increased blade area for strong hole shot, stern lift, grip and low-speed handling. The 13-inch pitch is intended for heavy loads or installations requiring lower-pitch performance.

⚠️ Common Signs of Failure

• Blades are bent, chipped, cracked or out of track
• The rubber hub slips and engine RPM rises without matching boat speed
• Propeller vibration increases with engine speed
• Cavitation, ventilation or poor acceleration develops after impact damage
• Hub splines, drive-pin surfaces or thrust faces are worn or corroded
