0309946 Evinrude/Johnson 10 x 9 1/4 Pin-Drive Aluminium Propeller | Genuine Used Part

🔧 Product Description

Genuine Evinrude Johnson 10 x 9 1/4 Pin-Drive Aluminium Propeller - Part Number: 0309946

A genuine used three-blade right-hand aluminium propeller for early Johnson and Evinrude V4 outboards using the pin-drive propeller shaft.

This 10-inch diameter x 9 1/4-inch pitch propeller uses the early non-thru-hub drive-pin arrangement. The lower pitch is suited to heavy loads, workboat use or hulls requiring maximum acceleration from the compatible early V4 gearcase.

🔌 Function

The propeller converts engine torque into thrust through a removable shaft pin. Its low 9 1/4-inch pitch provides strong acceleration and load carrying at the expense of potential top speed.

⚠️ 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
