How can you tell if your boat propeller requires replacement? There may be an obvious reason for doing so such as if your prop has sustained visible damage to a blade. However, even when your propeller is performing within manufacturer’s recommended guidelines, often there is room for performance improvement. Reasons for replacement include:
● Close inspection reveals broken or cracked blades.
● Upgrade to different materials such as aluminum or stainless steel.
● Upgrade to a different number of blades, from 3 to 4 for example.
● Upgrade to a larger size boat propeller to improve acceleration and top end performance.
● Want to carry a replacement propeller on board “just in case.”
