WebFeb 9, 2024 · When considering propellers, many boat owners get fixated on speed. They assume a prop that will make their boat go faster must be better. It’s more important to consider how a propeller can impact the entire boating experience. Speed is one element of that experience, but so are acceleration, economy, comfort and boat handling. WebPropeller: The propeller is typically used in mixers that are small and portable. This type of impeller tends to be heavy and quite expensive in larger sizes. Pitched Blade: A pitched blade impeller is used when a balance of flow and shear is required. It is especially useful in applications where 2 or more liquids are blended, and is well ...
