⚙️ Key Features

• Genuine Volvo Penta hydrodynamic blade geometry
• Designed for matched counter-rotating operation
• Marine corrosion-resistant alloy construction
• Factory-balanced propeller
• Must be paired with the specified companion propeller

🔌 Function

The propeller converts shaft torque into thrust and forms one half of the matched counter-rotating Volvo Penta propeller system.

⚠️ Common Signs of Failure

• Blade damage or deformation
• Spline or hub wear
• Reduced vessel performance
• Incorrect pairing with the companion propeller

🛠️ Service Notes

• Wedge the blades or lock the shaft so nothing can turn while the nut is slackened or tightened, with the drive out of gear and the engine unable to start
• Clean the shaft and hub bore, check the splines or taper are unmarked, and grease them with Volvo Penta propeller shaft grease — this is what lets the propeller come off again next time
• Refit the thrust washer, spacers and hardware in the same order they came off, and use a new lock washer, tab washer or split pin rather than the old one
• Tighten the propeller nut to the figure in the workshop manual for your installation and lock it positively; a propeller that works loose is rarely found again
• With the propeller off, check the blades for edge damage and distortion and clear any line from behind the hub — have a damaged propeller reconditioned rather than run on
