Can I save energy in my boat by changing my propeller?

    Yes, several aspects of propeller design can increase the efficiency of power input to power output.

    Number of blades – slightly increases efficiency.
    Diameter of propeller – can have a large effect on efficiency

    As a caveat, there are several other aspects to the design that need to be in place for these variable to sync up and produce a more efficient propeller – and, additionally, they may not be suited for certain boating conditions, eg; large diameter propeller in the shallows.
