The propeller is essential to the boat’s operation. Normally functioning propellers rotate without vibration and provide the best handling and fuel economy. Dented or damaged propellers, on the other hand, are uneconomical and can even damage the engine in the worst case.

You should carefully inspect your propeller every spring and autumn during boat maintenance and keep an eye on its condition throughout the boating season. You should always check the propeller and its condition if the boat or engine has touched bottom or been subjected to some other impact.

Maintenance
Modern propellers are extremely durable and will not corrode easily even in challenging weather conditions. You should nevertheless detach the propeller and grease the propeller axle with high-quality, water-resistant Vaseline in connection with boat maintenance. You can file away small scuff marks on the propeller blades yourself, but propeller repairs should be left to professionals in order to maintain the balance of the boat. In case of major damage, the propeller must be replaced if a significant quantity of material is missing from the blades.

Follow the engine manufacturer’s instructions for reattaching the propeller. When remounting the propeller, you should also check the oil level and radial shaft seals of the outboard engine’s angle transmission and the condition of the engine frame and anti-corrosive zinc anodes.
